Modlog, which includes a site ban—something only admins can do.
The community bans also include communities that aren’t moderated by any instance admins, and some that are only moderated by a single person who likely isn’t aware of actions taken under their community’s name.
Yeah that’s true. I meant more that they’d carry a copy of the site ban record in all the communities hosted by that instance and federate that even when you’re a remote user, it would treat it the same as a community ban from all communities on that instance but only be a single entry and most importantly would apply to every community on that instance.
The way they do it now is great but as it is the flaw is that they can participate in communities they never participated in before, which can be taken advantage of by malicious users in the same way as the old method where they weren’t given community bans at all.
