- From a technical standpoint: There’s no karma, just tracking amounts of posts/comments.
- There’s no automod to enforce it (Well maybe idk, not integrated I know that much.).
- There’s also the fact that the entirety of of the lemmy fediverse probably gets less posts overall each day then r/funny gets in just spam. It’s really easy to manually boop 5-10 spammers in a given day. 5-10,000 though? Not happening. Top that off with even a small percentage who might be trying to dodge technical hurdles put in their way? Lot harder.
