I actually really prefer the approach where you don’t need mods to step in. That’s the best part of Discourse’s approach to flagging. But the concern about getting notified about edits is spot on. However, it should be the flaggers who flagged in the first place getting the notification IMO, not the mods getting notified:
I opened this: Notification to flagger(s) when a flagged post is edited?
I disagree about that. That pushes against the learn-by-editing approach. The goal is not just that one post is fixed, the goal is that people learn to avoid the bad patterns overall, and if it takes some people more than one edit to learn what’s acceptable, fine.
