Boy oh boy where do I begin? For starters, the Minecraft YT stans are pretty hectic (and what's worse is that some of them just don't know any better). Another is the BTS stans, they can pretty belligerent too. The My Hero Academia community can also be pretty gross to be around (particularly with shipping, it can get aggressive). I don't know if this counts as a community but the people who use "dark humor" as a means to be a *not so nice person, use your imagination* get on my nerves a lot because they don't even try and get laughs, they just thrive off negativity. The internet is a dirty pool.
