@evenwicht@lemmy.sdf.org complained about this the other day, but I just experienced it first-hand.

A lemmy.world user got instance-banned on lemmy.world, and the result was their post in one of my communities created and based on lemmy.sdf.org got automatically removed. How the fuck is that a sanctioned inter-instance functionality?

That’s absolutely squirrel turds to me. It sort-of makes sense if my own instance admin were to ban that user, but reaching across instance lines to nuke posts is just wild.
