Okay but you can always make your own shitposting community on your own instance with your own rules if you feel so strongly against the rules. That option simply was not available on Rddit. The point of Lemmy isn’t that no one abuses their mod and admin powers ever, but that the system is set up so that you can just go to another Lemmy server, which simply was not available on Rddit if you pissed off the site admins.
Although I personally find Lemmy users nicer and moderation better on average, their character is not the point. It is merely the result of an imperfect but better system than R*ddit.
