This could be either site tools or popular Reddit bots that need to be ported over.
I think a big reason so many subs are going dark tomorrow is due in large part to how hard Reddit is about to make moderation - so it might make sense to make this an area of focus for Lemmy.
I’m no moderator but from what I’ve seen, it’s easier to setup bots to automod subreddits which apps. They can’t manually review every single comment on threads like the AMA of spez, they need tools like bots to help them delete or edit comments like « fuck u u/spez ».
