While on it, it would be cool to integrate this plugin into the core.
I think we briefly discussed about this somewhere but it has been deleted since I believe. So I repeat: we practice this with success, even though not with the plugin. We have approve unless trust level set to 1 and we regularly lock people to trust level 0 if we don’t trust them for whatever reason.
Of course most of the time suspending temporarily or for good is what we do. But for some cases forcing the user through moderation is a nice tool to have. Some users have character from the fiction novel “Dr Jekyll and Mr Hyde”. Mostly they produce good or harmless content but then they freak out every now and then (typically on weekends) and show their toxic side. If they clearly can’t help it, we can let them keep their account and they can still post their good stuff.
Would be nice to promote this practice with real support even if you already have two ways to achieve it if you know about it.
