It's more likely that the project itself will disappear into irrelevance as soon as AI scrapers bother implementing the PoW (which is trivial for them, as the post explains) or figure out that they can simply remove "Mozilla" from their user-agent to bypass it entirely.

PoW increases the cost for the bots which is great. Trivial to implement, sure, but that added cost will add up quickly.

Anyway, then we'll move on to tarpits using traditional methods to cheaply generate real enough looking content that the data becomes worthless.

Fuck AI scrapers, and fuck all this copyright infringement at scale. If it was illegal for Aaron Schwarz it's definitely illegal for Sam Altman.

Frankly, most of these scrapers are in violation of the CFAA as well, a federal crime.

No, the article estimates it would cost less than a single penny to scrape all pages of 1,000,000 distinct Anubis-guarded websites for an entire month.

Once you've built the system that lets you do that, maybe. You still have to do that, though, so it's still raising the cost floor.

Don’t forget signed attestations from “user probably has skin in the game” cloud providers like iCloud (already live in Safari and accepted by Cloudflare, iirc?) — not because they identify you but because abusive behavior will trigger attestation provider rate limiting and termination of services (which, in Apple’s case, includes potentially a console kill for the associated hardware). It’s not very popular to discuss at HN but I bet Anubis could add support for it regardless :)

Yes, fuck them. Problem is Anubis here is not doing the job. As the article already explains, currently Anubis is not adding a single cent to the AI scrappers' costs. For Anubis to become effective against scrappers, it will necessarily have to become quite annoying for legitimate users.

To the best of my knowledge, it never really worked.

Yes, it probably works in the lab, in carefully picked conditions, but in the wild I've yet to see any effect whatsoever. Nobody in the AI communities seems to be complaining about it, models keep getting better, and people even intentionally trained on poisoned images just to show it can be done.

IMO on the long end it's a complete dead end of a strategy. Models are many, poisoning can't target everything at once. Even effective poisoning can be just dealt with by finding the algorithm that doesn't care about it.

Maybe. But what’s happening is ”copyright for thee not for me”, not a universal relaxation of copyright. This loophole exploitation by behemoths doesn’t advance any ideological goals, it only inflames the situation because now you have an adversarial topology. You can see this clearly in practice – more and more resources are going into defense and protection of data than ever before. Fingerprinting, captchas, paywalls, login walls, etc etc.

That's what it's for, isn't it? Make crawling slower and more expensive. Shitty crawlers not being able to run the PoW efficiently or at all is just a plus. Although:

Sadly the site's being hugged to death right now so I can't really tell if I'm missing part of your argument here.

And flag themselves in the logs to get separately blocked or rate limited. Servers win if malicious bots identify themselves again, and forcing them to change the user agent does that.

The default settings produce a computational cost of milliseconds for a week of access. For this to be relevant it would have to be significantly more expensive to the point it would interfere with human access.

...unless you're sus, then the difficulty increases. And if you unleash a single scrapping bot, you're not a problem anyway. It's for botnets of thousands, mimicking browsers on residual connections to make them hard to filter out or rate limit, effectively DDoSing the server.

Perhaps you just don't realize how much did the scraping load increase in the last 2 years or so. If your server can stay up after deploying Anubis, you've already won.

Re:Why are anime catgirls blocking my access to the Linux ke... by dale_glass on Thursday August 21, 2025 @05:28AM (#44970735)
How is it going to hurt those?

If it's an actual botnet, then it's hijacked computers belonging to other people, who are the ones paying the power bills. The attacker doesn't care that each computer takes a long time to calculate. If you have 1000 computers each spending 5s/page, then your botnet can retrieve 200 pages/s.

If it's just a cloud deployment, still it has resources that vastly outstrip a normal person's.

The fundamental issue is that you can't serve example.com slower than a legitimate user on a crappy 10 year old laptop could tolerate, because that starts losing you real human users. So if let's say say user is happy to wait 5 seconds per page at most, then this is absolutely no obstacle to a modern 128 core Epyc. If you make it troublesome to the 128 core monster, then no normal person will find the site usable.

Re:Why are anime catgirls blocking my access to the Linux ke... by throwawayffffas on Thursday August 21, 2025 @06:32AM (#44971091)
It's not really hijacked computers, there is a whole market for vpns with residential exit nodes.

The way i think it works is they provide free VPN to the users or even pay their internet bill and then sell the access to their ip.

The client just connects to a vpn and has a residential exit IP.

The cost of the VPN is probably higher than the cost for the proof of work though.

Re:Why are anime catgirls blocking my access to the Linux ke... by seba_dos1 on Thursday August 21, 2025 @05:41AM (#44970815)
> How is it going to hurt those?

In an endless cat-and-mouse game, it won't.

But right now, it does, as these bots tend to be really dumb (presumably, a more competent botnet user wouldn't have it do an equivalent of copying Wikipedia by crawling through its every single page in the first place). With a bit of luck, it will be enough until the bubble bursts and the problem is gone, and you won't need to deploy Anubis just to keep your server running anymore.

Re:Why are anime catgirls blocking my access to the Linux ke... by mfost on Thursday August 21, 2025 @05:35AM (#44970775)
I thought the point (which the article misses) is that a token gives you an identity, and an identity can be tracked and rate limited.

So a crawlers that goes very ethically and does very little strain on the server should indeed be able to crawl for a whole week on a cheap compute, one that hammers the server hard will not.

Re:Why are anime catgirls blocking my access to the Linux ke... by throwawayffffas on Friday August 22, 2025 @08:58AM (#44984089)
Sure but it's really cheap to mint new identities, each node on their scrapping cluster can mint hundreds of thousands of tokens per second.

Provisioning new ips is probably more costly than calculating the tokens, at least with the default difficulty setting.

The explanation of how the estimate is made is more detailed, but here is the referenced conclusion:

>> So (11508 websites * 2^16 sha256 operations) / 2^21, that’s about 6 minutes to mine enough tokens for every single Anubis deployment in the world. That means the cost of unrestricted crawler access to the internet for a week is approximately $0.

>> In fact, I don’t think we reach a single cent per month in compute costs until several million sites have deployed Anubis.

Wasn't sha256 designed to be very fast to generate? They should be using bcrypt or something similar.
Re:Why are anime catgirls blocking my access to the Linux ke... by throwawayffffas on Wednesday August 20, 2025 @06:07PM (#44967035)
Unless they require a new token for each new request or every x minutes or something it won't matter.

And as the poster mentioned if you are running an AI model you probably have GPUs to spare. Unlike the dev working from a 5 year old Thinkpad or their phone.

Re:Why are anime catgirls blocking my access to the Linux ke... by _flux on Thursday August 21, 2025 @04:33AM (#44970455)
Apparently bcrypt has design that makes it difficult to accelerate effectively on a GPU.

Indeed a new token should be requested per request; the tokens could also be pre-calculated, so that while the user is browsing a page, the browser could calculate tickets suitable to access the next likely browsing targets (e.g. the "next" button).

The biggest downside I see is that mobile devices would likely suffer. Possible the difficulty of the challange is/should be varied by other metrics, such as the number of requests arriving per time unit from a C-class network etc.

Re:Why are anime catgirls blocking my access to the Linux ke... by debugnik on Wednesday August 20, 2025 @05:30PM (#44966701)
That's a matter of increasing the difficulty isn't it? And if the added cost is really negligible, we can just switch to a "refresh" challenge for the same added latency and without burning energy for no reason.
Re:Why are anime catgirls blocking my access to the Linux ke... by Retr0id on Wednesday August 20, 2025 @05:50PM (#44966890)
If you increase the difficulty much beyond what it currently is, legitimate users end up having to wait for ages.
Re:Why are anime catgirls blocking my access to the Linux ke... by debugnik on Thursday August 21, 2025 @01:32AM (#44969334)
And if you don't increase it, crawlers will DoS the sites again and legitimate users will have to wait until the next tech hype bubble for the site to load, which is the reason why software like Anubis is being installed in the first place.
Re:Why are anime catgirls blocking my access to the Linux ke... by shkkmo on Thursday August 21, 2025 @11:42AM (#44974176)
If you triple the difficulty, the cost of solving the PoW is still neglible to the crawlers but you've harmed real users even more.

The reason why anubis works is not the PoW, it is that the dev time to implement the bypass takes out the lowest effort bots. Thus the correct response is to keep the PoW difficulty low so you minimize harm to real users. Or better yet, implementing your own custom check that doesn't use any PoW and relies on ever higher obscurity to block the low effort bots.

The more anubis is used, the less effective it is and the more it harms real users.

Re:Why are anime catgirls blocking my access to the Linux ke... by kbelder on Thursday August 21, 2025 @01:07AM (#44969219)
If you use one solution to browse the entire site, you're linking every pageload to the same session, and can then be easily singled out and blocked. The idea that you can scan a site for a week by solving the riddle once is incorrect. That works for non-abusers.
Re:Why are anime catgirls blocking my access to the Linux ke... by shkkmo on Thursday August 21, 2025 @08:04PM (#44979672)
Well, since they can get a unique token for every site every 6 minutes only using a free GCP VPS that doesn't really matter, scraping can easily be spread out across tokens or they can cheaply and quickly get a new one whenever the old one gets blocked.

I don't think it's relevant to debate if anime or other forms of media is objectively better. But as someone who has never understood anime, I view mainstream western TV series as filled with hours of cleverly written dialogue and long story arches, whereas the little anime I've watched seems to mostly be overly dramatic colorful action scenes with intense screamed dialogue and strange bodily noises. Should we maybe assume that we are both a bit ignorant of the preferences of others?

Let's rather assume that you're the kind of person who debates a thing by first saying that it's not relevant to debate, then putting forward a pretty out-of-context comparison, and finally concluding that I should feel bad about myself. That kind of story arc does seem to correlate with finding mainstream Western TV worthwhile; there's something structurally similar to the funny way your thought went.
Re:Why are anime catgirls blocking my access to the Linux ke... by timcambrant on Thursday August 21, 2025 @07:44AM (#44971544)
I feel the same. It's a distinct part of nerd culture.

In the '70s, if you were into computers you were most likely also a fan of Star Trek. I remember an anecdote from the 1990s when an entire dial-up ISP was troubleshooting its modem pools because there were zero people connected and they assumed there was an outage. The outage happened to occur exactly while that week's episode of X-Files was airing in their time zone. Just as the credits rolled, all modems suddenly lit up as people connected to IRC and Usenet to chat about the episode. In ~1994 close to 100% of residential internet users also happened to follow X-Files on linear television. There was essentially a 1:1 overlap between computer nerds and sci-fi nerds.

Today's analog seems to be that almost all nerds love anime and Andy Weir books and some of us feel a bit alienated by that.

Re:Why are anime catgirls blocking my access to the Linux ke... by cdrini on Thursday August 21, 2025 @09:00AM (#44972234)
I think I'd push back and say that nerd culture is no longer really a single thing. Back in the star trek days, the nerd "community" was small enough that star trek could be a defining quality shared by the majority. Now the nerd community has grown, and there are too many people to have defining parts of the culture that are loved by the majority.

Eg if the nerd community had $x$ people in the star trek days, now there are more than $x$ nerds who like anime and more than $x$ nerds who dislike it. And the total size is much bigger than both.

Especially because (from my observation) modern "nerds" who enjoy anime seem to relish at bringing it (and various sex-related things) up at inappropriate times and are generally emotionally immature.

It's quite refreshing seeing that other people have similar lines of thinking and that I'm not alone in feeling somewhat alienated.
