I like that idea because it solves the problem of someone spinning up a dozen communities across several popular instances and repeatedly banning a user and writing defamation in the modlog. Which is a very abusive tactic I’ve seen used by various individuals.

While I’m an anarchist and I always question authority, most people aren’t. Most people implicitly trust mods. So abusing people’s trust like that can be very effective as a means of reputational abuse. It’s propaganda.
