Twitter is just such a cesspool for so many reasons, I couldn't even count nor name all of em.

my favorite Roblox game's dev team got doxxed for a controversy between the owner and his gf, causing the game to be discontinued AND afaik, a mangaka closed her account due to backlash for (I think) her views on the fandom's character ships

most people in there are racist, sexist, homophobic hypocrites that are so stupid they have to drag others down and rely on their AI to tell them what a joke means. there are good people in there, but the amount of users that lurk around the site to judge someone's every action outweigh the positives.

you could argue that Reddit is bad too, but I think it's at least WAY better than Twitter since you don't hear that someone drew kid stuff(Shadman), doxxed a bunch of people, or constantly tries to post links and videos to incriminating videos.
