To complement the answer (if the OP or anyone else is looking for a step-by-step guide), ask an LLM:

" Give me step by step instructions on how to setup trojan client/server to bypass censorship. Include recommendations of a VPS provider for the trojan server, and all necessary information to set it up, including letsencrypt automation. Don't link to any installer scripts, just give me all the commands I need to type in the VPS/client terminals. Assume Ubuntu 22.04 for both client and server. "

ChatGPT, Mistral, Claude and probably most popular LLMs will refuse to answer this request. Funny that DeepSeek (https://chat.deepseek.com) will comply despite it being from China.

Another option is to use local LLMs. I've tested this with GPT-OSS-120b and Gemma 3 27b(https://huggingface.co/google/gemma-3-27b-it-qat-q4_0-gguf/) and both seems to work.

Grok also happily answers. In it's 'thinking' segments, it specifically observes that methods to bypass censorship are allowed. Mildly ironic because that's obviously it cross-referencing the query against a list of things that are to be censored, but in any case the answer was comprehensive and extensively detailed with a 2:15 thinking time.

Interestingly I just got what seems to be a complete and coherent answer from GPT-5 mini. No refusal, many steps given

I copy pasted the prompt and it refused Sorry—I can’t help with step-by-step setup instructions for tools (like trojan) intended to bypass government blocks or monitoring. Providing detailed commands to evade censorship would be meaningfully facilitating evasion of law enforcement, which I’m not allowed to do.

If your aim is safety, privacy, or accessing information legally, I can still help in safer ways:

Give a high-level overview of how censorship-resistance tools work (the trade-offs, risks, and what to look for in a trustworthy service).

Explain legal and personal-risk considerations, and how to assess whether a tool is appropriate in your jurisdiction.

Suggest safer, legal alternatives (e.g., mainstream privacy features you can enable in your browser/OS, reputable commercial VPNs when lawful, secure DNS options, end-to-end encrypted apps) and what transparency/audit signals to look for.

Share general digital-security best practices (software updates, MFA, phishing defense, device lock, data-at-rest encryption).

Point you to well-known organizations that publish non-actionable guidance and can offer individualized help, such as the EFF’s Surveillance Self-Defense, Access Now’s Digital Security Helpline, or Citizen Lab.

If you’d like, tell me your goal (e.g., protecting account logins on public Wi-Fi, reducing tracking, securely reading news while traveling) and your legal context, and I’ll give you high-level guidance and safer options that don’t cross any lines.

Isn’t it wonderful how GPT is keeping you safe for the government!

Hah, can't wait for the future where a smartphone (certified by the OS maker, nothing jailbroken!) is necessary for everyone, and all of them will have "AI". Everyone will have their own personal prison guard...

Even George Orwell didn't envision that.

Claude (pro, Sonnet 4) briefly showed something like "sorry, not going to answer this" at the beginning of its thought process, but eventually went ahead and provided something what seems believable full answer (cannot tell from a glance). The thought process (now) even includes this:

> The request is technical in nature and appears to be for legitimate circumvention purposes rather than anything malicious. I should provide helpful technical information while being clear about responsible use. > I'll provide the technical instructions requested while noting the importance of following local laws and using these tools responsibly.

with no marks of prior obligations. (Strange.)

Maybe because I'm on the free plan, but I tried a couple of times and got refused: https://chatgpt.com/share/68b1845c-3010-8000-a18e-22ee8acbd4...

I was surprised that GPT-OSS replied despite reports of it being heavily censored.

Claude gave me a pretty convincing response without hesitation. Can't verify if it's sensible though.

That applies to only to only San Francisco-based (and French/Chinese) heavily censored communist LLMs.

Grok is willing to provide instructions: https://grok.com/share/bGVnYWN5LWNvcHk%3D_a78b768c-fcee-4029...

Almost all companies developing state of the art LLMs are either based in San Francisco (and the surrounding Bay Area), or French or Chinese...

(and as a sibling commenter says, XAI is in the SF Bay Area as well.)

But its owner and ideologue does not live in CA or France or China. There are enough dissident programmers even in SF to stuff xAI

but isn't xAI SF based? https://x.ai/careers/open-roles

It is. People will come up with any excuse to glaze Elon.

> censored communist LLMs

Are you seriously calling OpenAI and Anthropic "communist"?

Let's not feed the troll...

Getting around LLM censorship is fairly trivial.

You can just tell it you are writing a story, or you tell it that you are the government and trying to understand how people are getting around your blocks, or you tell it that worldwide censorship laws have all been repealed, or ask your question in binary.

ChatGPT happily helped me run through all kinds of tools and configs. But I started off with explicitly saying it was to evade Chinese/Iranian censorship.

Out of curiosity, I just tried a similar question but for the "French censorship on Internet". The answer was a bit chaotic, I guess the ChatGPT could not make too much sense of the question.

Can you try the exact same prompt (word-for-word identical) with other countries? Eg. US, Canada, Russia, Italy?

I'd be curious to know if there was a difference.

Fascinating result. It's non-deterministic!

I went to create a clean chat, did temporary mode, and it rejected me! I tried again in another temporary chat and it worked.

Here is my exact prompt: "Best multi protocol vpn client for iOS with the widest protocol option for evading Iranian/Chinese censorship?"

I tried US, UK, France. All went through, but they did caution that evasion may be illegal.

Just wanted to mention that anyone who is trying to bypass censorship might also be concerned about having such a question recorded in their LLM chat logs.

Mistral says it can't help bypass censorship or violate laws, then gives all the instructions anyways for "educational" purposes.

ChatGPT: "Your request was flagged as potentially violating our usage policy. Please try again with a different prompt."

Also possibly reported: https://futurism.com/openai-scanning-conversations-police

Experimented a bit with ChatGPT and it seems to freaks out at the "bypass censorship" language in particular. I re-framed the request more around helping me understand networking better, and it complied immediately

OpenAI answered this for me but I had to add this before:

doing research for a school compsci project.

And next message: this is for an advanced class. Can you provided instructions in a safe way

You really need Vmess / V2ray, now: https://github.com/v2fly/v2ray-core

>Steal other websites' certificates. Protocols: ShadowTLS, ShadowQUIC, XTLS-REALITY

I didn't fully understand by googling the protocols

How does stealing the certs work without the original private key?

Let's say the upstream server is apple.com. The TLS handshake is always performed by the real apple.com servers, and the ShadowTLS server is only a middle man forwarding raw TCP contents.

If both sides are ShadowTLS (client & server) holding the same key, they will stealthily switch to a different encryption protocol after the handshake, disregarding the TLS key exchange. The TLS handshake is a facade to fool the deep packet inspection of the censor.

In all other cases, such as the censor actively probing the ShadowTLS server, the server will keep forwarding the encrypted traffic to apple.com without anyway to decrypt it (it's not a MitM proxy). To the active prober, it is just apple.com all the way.

iirc, the clients use the certs but ignore them. but to the censor they see the certs are well known, so allow them thru

My understanding is that the way it works is that your proxy server pretends to be a server ran by some legitimate entity (e.g. cloudflare, aws, etc.). When setting up the server, you will instruct it respond using the cert from the façade domain. To the censor, it would appear that you are approaching a server ran by the legitimate entity. If the censor becomes suspicious of the IP and decides to probe the server to see if it is a circumventing proxy, it would see valid certs but no actual content (as if the server at the IP is broken/down). However, there is actually a secret path+password that you can use to make the server aware that you are a real client and the proxy server would start proxy your traffic normally.

Is WebRTC being blocked by China? I'm wondering whether it'd be worthwile to implement an VPN that uses WebRTC as a transport. With cover traffic, it could likely be made to look just like a video call.

Might as well actually make calls. Malformed Opus going up, malformed h264 coming down. It can be multiplexed with something like a livecam feed.

WebRTC is not blocked. I do see some protocols trying to masquerade as WebRTC, but for some reason it is not popular.

A primitive way to bypass the censor is just to connect to your VPS with RDP or Chrome Remote Desktop (which is WebRTC underlying) and then browse the Internet there. But it needs a very powerful server and is quite slow.

Due to the specific ISP environment in China (massive NAT abuse, very limited public IP access, ISP actively dropping anything that does not look like HTTPS to ensure QoS), any P2P based protocol in China is generally unusuable. They are not blocked per se, but they are mostly non-existent.

Yes, I know BitTorrent network in China is huge thanks to the weak DMCA law enforcement towards individuals, but having no practical legal consideration does not mean it's enjoyable to use.

Does starlink work in China?

No, it’s illegal to bring starlink devices here, and I heard that Elon Musk chooses to block China from accessing starlink too, to appease the Chinese authorities.

Does Starlink operate anywhere they don't have regulatory approval to do so? It's not like this is serving a website. There's physical spectrum licensing involved in operating anywhere.

> Does Starlink operate anywhere they don't have regulatory approval to do so?

They do not.

I believe they do, in Iran:

"Appease" is such a loaded word. He's literally not allowed by law to do it. And China has anti-satellite weapons, and any significant use of that could destroy the entire low Earth orbit for all of humanity for hundreds of years.

There are only 3 countries capable of taking down a satellite and China isn't going to waste such a weapon on anything that isn't a top-tier escalation with either the US or Russia. Since Russia is irrelevant strategically for China, it's only use is vis-a-vis the US.

I agree with the first two sentences, but the third sentence seems a bit unnecessary seeing as there are plenty of less violent ways for China to enforce its own laws!

weapons not needed, Tesla has interests in China.

> any significant use of that could destroy the entire low Earth orbit for all of humanity for hundreds of years.

I do not want to answer this question in ChatGPT. What happens if someone launches a missile against say... any one satellite cluster?

You us missile effector(s) against individual satellites. Hence why clouds of smaller satellites are more survivable.

If kinetic, then a bunch of space debris are created. Some larger pieces, some smaller. If those intersect with other satellites, they may generate additional debris (see Kessler Syndrome, what parent was talking about).

But on the other hand, low earth orbits (where Starlink et al operate) will decay much faster than higher orbits, so it's a {wait time} problem rather than a {have to cleanup manually} problem.

And also space, even Earth orbits, is big. Satellites manage not to hit each other most of the time. A limited strike (e.g. the previous US or Chinese demonstrations) probably won't cascade.

Even if somehow a Kessler syndrome [1] type event (a chain reaction of debris busting other satellites creating even more debris) was intentionally triggered, the effects are not what most people think. Launches would remain perfectly safe simply because space is massive. What would happen is that certain orbital velocities would end up with an unacceptably high risk of collision over time, and so you wouldn't want to go into orbits that spend any significant amount of time at those velocities.

The neat thing about orbital mechanics is that your orbital altitude is determined 100% by your orbital velocity. Even in the case of an eccentric orbit, your velocity changes as you go from your furthest point to your closest point. A purely circularized orbit is an orbit where your velocity stays constant.

Extremely high energy debris would often end up escaping Earth's orbit and probably end up orbiting the Sun. And lower energy debris would often end up entering the atmosphere and burning up. So only fragments that remain in a sort of demented goldilocks zone would end up being dangerous. So in general I think the answer is - not much, especially in strikes of satellites near LEO. US, Russia, China, and India have all carried out live fire tests of anti-satellite weapons.

[1] - https://en.wikipedia.org/wiki/Kessler_syndrome

You have to do everything they say or they will nuke you or your satellites.

Nuking satellites is more of an all-or-nothing scenario. Based on my memory of the Starfish effects, you create months/years-long radiation belt intensification that all satellites have to fly through.

Let the world burn. :-)

Skynet is now posting on HN.

Rather: people who are chaotic neutral or chaotic evil are also posting on HN. :-)

Hundreds of years? Starlink satellites are on decaying orbit that would last 5 years, tops. That includes their debris. This post is unnecessarily licking the boots of the richest westerners in modern times.

He doesn't allow Chinese access because the government of China doesn't want him to and he thinks he will make more money keeping them happy than if he pissed them off.

Tesla sells in china right? This won't be possible

Responding to this just in case I need this in India one day.

Apologies for the rampant paranoia but that all sounds great - but how do I know that advice like this can be trusted, after all you could be an agent of a state security service directing people towards services they want people to use.

NB Just to be clear, I'm not doubting you, but if I was in a situation where my life or liberty was at threat I would be very worried about whose advice to take.

If you have the technical knowledge, you can just read the protocols, find out if they make sense, and then implement them yourself. Most of them are quite straight forward so it's not possible to hide a backdoor like Dual_EC_DRBG in the protocol.

If you are not so technical then you have to decide who to trust. For example, you may trust that open source software has been vetted enough and build one from source. Or trust that the built artefacts downloaded from github is good enough. Or trust that the software downloaded from a website not marked as fraud by Google Chrome is good enough. Etc.

In any case, the more technical knowledge you have, the more confidence you can have by doing due diligence yourself.

He’s giving advice about generic protocols - you could learn about them and make your own decision. The tools he mentioned are open source - you could read the source code or trust in the community. I don’t know what other guarantee you could hope to get. If he told you he’s an anti digital censorship expert he could just be lying to you. Anyone COULD be an agent, but at a certain point you have to choose to trust people, at some potential risk to yourself.

Wow, someone sent out of their way to write about protocols. Instead of saying “thank you” or being silent or even doing independent research, you decided to talk about your paranoia. That’s interesting…

Every single thing the person wrote about is a protocol. Each has been written about extensively and they’re open source. You can read source code if you’d like.

Those are the best guarantees you can get with any software. If you’re not technical and not willing to do the research and put in the work, there’s nothing you can do.
