Please leave this fella alone. I know of him. We really do have some odd characters here on lemmy and he's one of them. Don't quote me but I'm pretty sure this is not someone on drugs or playing around he's genuinely schitzo and often struggles with thoughts of suicide. He doesn't need any more trouble or attention. Very different and not really able to interact with the world in the way the majority of us do. Try not to bully. I know there's a lot of "why doesn't he just?" And "he shouldn't be here" but I really urge you to just let him freak in whatever space as long as it doesn't mess with anyone else too much. Feel free to check out his posts and comments for your own entertainment if seeing someone else's troubled mind is your jam just keep it to yourself. If the admins of his instance wanna ban him you can appeal to them I guess.
