Did you ever have that feeling on reddit of “I better word my post just right, otherwise AutoMod will take it down”? Some subs had such strict auto moderating that it was a crap shoot to post something. Not so here. I know there’s value in moderation, and I’m sure Lemmy/kbin/etc. will add more of it with time. But, for now, it was just nice to not be nervous when I was submitting a post here.
I’ve used that mechanism as a moderator intentionally.
Some subs just get a lot of low effort, low quality posts, by setting certain automated rules, you can filter out people that don’t read any submission instructions. In practice those are nearly always low effort.
A simple example is “set post flair to X before clicking on submit” and if they don’t do that, just autoremove the post and tell them why and to contact the mods if they disagree.
Anyone that cares will delete and resubmit correctly. Anyone that doesn’t really care will move on to something else.
