Also:
-Forum admins reading your PMs; the reason assemblergames stayed up was the admins did just this.
-PLEASE SIGN UP TO DO ANYTHING.
-Forum paywalls (seriously some do this shit).
-Forum moderator more ban happy than LTG in his stream chat.
-Jannies censoring discussion to avoid getting nuked by someone else.
A lot of people forgot one of the reasons Discord/Reddit got so fucking big was the lack of moderation at one point or little moderation. Then when a scandal happened, just throw moderation at the problem by the time it has critical mass. Whoopsies. Now Discord went from the cool kids club chat platform to groomer central overnight, and Reddit went from the days of /r/watchpeopledie and edgy shitpost subs to posting there means it's like walking on eggshells. But nobody will move because it's big already, and if you use the same tricks to get big you'll be thrown off hosts for hate speech.
