Communities really should have a report button so that when problematic communities are created, they can be directly reported to the admins. I’ve run into a couple problematic communities already, one of which (which has thankfully since been removed) was making transphobic posts, but just recently I’ve run into a community (!letsfightbigotry@lemmy.world) whose main user is very blatantly trying to justify pedophilia. Reporting the posts on the community isn’t very useful if they’re only going to go to the user responsible for the community, since they can just discard the reports so they never reach the admins.

(Also if such a feature existed, to cut down on spam I’d imagine there would be a way to flag known reputable communities as “acceptable” so any reports about such known good communities can be safely discarded.)
