I'm a bit of an internet deep diver. I don't like, dox people or go out looking for terrible things, or anything. I just tend to notice little weird things sometimes and then follow the thread for a while to see where I end up.

Linux-is-best was definitely off, worryingly so. I'm not even sure that the things they posted about their real life, like their job, was accurate.

They also were not possible to engage with. It's just not what they were doing here. Online, there's no way to force a genuine interaction. Like, offline? I could look at them in the eyes and tell them something and they'd have to at least consider it. Online it's so much easier to harden yourself against that, or to click away, or to focus on a different comment that you can argue with instead. There's not really much benefit to engaging online with someone who isn't there to engage, which unfortunately means there's almost no way to help someone who is slightly crazy.

Them deleting their account is probably the best case scenario for them, although they are definitely the sort of person who has tons of accounts on other websites they switch between all day, so... Really, my point is that there's not anything anybody can do from here. You shouldn't feel bad about it, but you probably will for a bit, which is good because it means you've still got perspective and empathy.
