How fast were you going, though? lol
There’s a “purge post” button, which seems to actually remove content or access to it. I didn’t try it out yet, because there wasn’t a lot of moderation necessary so far, to be honest.
Some instances have rules against creating many communities without actively moderating them. I run an instance, too and I think, moderating more than a handful communities is not possible at a certain point.
