I actually have no idea who Hajo is. If they’ve been annoying in the past, and you banned them for it, it’s not really my place to figure out whether they deserved it. I only replied because yelling about it here is a sure fire way to get your comment flagged. Maybe you don’t mind but I felt that, spending far too much time here and watching a bunch of people do this repeatedly even though it’s against the rules, I might as well send people a reminder that there’s another option.

As for your Telegram chat: I actually genuinely do not care, and I mean this without trying to be smug or anything. I joined to ask about S8 stuff and eventually just met Dennis directly. Ironically both of us seem to have gotten too busy with work to actually get to a good solution for those and I never actually ended up installing Valetudo anyway. My friends occasionally tell me how great it is and I feel a little but of regret for not following up to get the exploit stable but I just put up with letting my vacuum do its thing without any of the smart features :( But yeah, I really don’t think I would have gotten any value from rejoining the chat so I didn’t. I’m actually kind of sorry I participated in the conversation I did, not really because I wouldn’t stand behind what I said but more that it was kind of a waste of time and low value to even respond. And clearly it made you upset, so considering I valued it at effectively zero and you definitely felt it was negative, I think the conclusion is pretty obvious.

One thing I do want to say, though: I feel like you frequently run into your project just causing you misery. I work on FOSS too, and arguably I work in a similar hacking-ish space too where random people show up and beg you for support, who don’t really bother to read the rules, etc. I get that this is frustrating. I ban plenty of people who drag down the place too. But I think that your garden that you’re trying to make might actually be causing you more trouble than it might be worth. I don’t wake up feeling drained that I have to interact with the community, in fact I actually appreciate talking to many of the members even if they can be annoying sometimes. I’ve had people occasionally claim they were unfairly treated (usually I disagree, of course) but I think the sentiment is largely positive. So, like, I just want to point out that it’s possible to enjoy what you do; it can be nice even if sometimes frustrated people show up. I just don’t want you to hate working on the things you’re doing.

I have yet to see anyone attack you, here or in any of the links people have provided. I don't know all the history of your interactions with these people, but it feels like you are playing the victim without cause.
