sexual harassment
We have this nostalgia for web forums on here, but my first 5 years online were spent like this:
2 years on a forum being constantly harassed by a guy who would "joke" about raping me, while the mods repeatedly banned him for miscellaneous trolling, only for him to come back in a few days with a new account
Then 3 years on a private forum that slowly became more and more right-wing, with the mods perfectly content with the situation because they were the ones driving it
sexual harassment
Mastodon instances are better than web forums, because if the mods on your instance are assholes, you can go to another instance and still keep in touch with your friends fairly easily.
Whereas jumping ship from a web forum meant losing touch with people or only communicating with them privately from then on.
