Like users that are known for a gimmick or that everyone sees alot?
I saw a comment the other day where they (Flying Squid) claimed to be in their 40s. Idk about mental health issues, but they are incredibly hostile/argumentative in comments.
For whatever this is worth, he is argumentative & unfriendly enough for him to be mentioned multiple times in this thread as a famous asshole. (Note, many comments have now been “removed by mod” - but they were there. Just mentioning it in case someone tries to Ctrl+F their name to verify.)
