2. You got one mention, Raptor told me you had replied. The groups open, you can take a look and then leave if you want. Nobody is making up theories about you.
3. It's not a "mob attack". Most of the people here were treated badly, which is what drove them to make these comments. The effect cannot precede the cause, that makes no sense. By the same reason, it is also not harassment. Posting about being being treated badly by someone is not harassment or an attack. If you don't want to be known for treating people badly, the solution is to not treat people badly.
4. To my knowledge, deepscanner isn't in the discord. I have no idea who they are.
5. On astroturfing, someone accused me of brigading when this came up on Reddit and I'll say the same thing here as I did there - I don't know most of these people, I didn't tell anyone to come here. I found out about this thread yesterday, and made my first comment at 16:58 on the 26th. Most of the discussion on this thread happened before my comment and before I was even aware of this thread. Again, the effect cannot precede the cause. Nobody on the discord told anyone to post either. However, there is plenty of evidence of Hypfer brigading, you only need to read the dust announce where he writes "Speak up. In your own words. With your own thoughts. Say something." in response to the subreddit creation. This message was read by 9,790 people. This is a super clear violation of reddits brigading rules.
I notice however, that you say "I never heard about valetudo before", but you also mentioned "We don't need you to save us from the creator of this software". I have mentioned in posts on other platforms that I primarily post my experience to protect / warn unsuspecting people about the Valetudo community, but, I said nothing to that effect in my comments here. The only way you'd have been prompted to write that, is if you'd read my posts on other platforms, yet you claim to have never heard of Valetudo ... whoopsie.
I agree with you that open source developers face harassment, I've seen it happen myself. But, in this case, things are the other way around. Hypfers behavior is awful, there are threads full of of people on reddit that Hypfer has been rude / abusive to. There's an entire discord server with 85 members and counting, the majority of which have been on the receiving end of harassment and just want to talk vacuum modding. Don't believe me? search "site:reddit.com hypfer" on Google and start reading, there's piles of it. Running an open source project does not entitle you to abuse people. There's no other open source project that I can say "just chuck site:reddit.com <developers name> into Google and start reading, you'll find them harassing people."
Of course, I'm also a victim. They accused me of gaslighting them, told me I was stupid, banned me and then spent days after ridiculing me in the Telegram group with thousands of members. I saw screenshots likening educating me to taking a 4 year old to university, and another saying something akin to "I pity the spouses of the people I've banned here", while also playing the "woe is me" card claiming that I asked them to implement HTTPS support when I explicitly stated the opposite. This stuff is extremely clear harassment. To be clear, I did nothing to provoke this behavior, I was asked why I thought HTTPS support on the robot was a good idea, I explained, got banned because Hypfer didn't agree. Hypfer then wrote a FAQ on the subject. Any engineer well versed on the topic would tell you the majority of the stuff in the FAQ entry is wrong.
Since my ban, I've learned that my story is a common theme, users will join the telegram for support and ask questions, only to be abused, banned, and then publicly ridiculed for days afterwards. Even more clear cut things like "Docs say that if X happens I should ask on the Telegram group, I did and immediately got banned". I've received countless messages from users who have been on the receiving end of this harassment.
This situation makes for a terrible example of harassment open source developers face, because in this specific case, there's more harassment towards the users than from them. If you want a nicer example, I'd suggest going and looking at the Jellyfin devs or something, they definitely receive their fair share of unwarranted shots from users.
