Im not sure if there is something viable apart from Miserable users although i dont think miserable users does what hell ban does .
One of my moderators has requested a troll trap called Hell ban, basically once this user is in a certain usergroup no one else can see their posts and its as if everyone is just ignoring them.
A very old mod was here :

Anyone seen something like it for VB4 ?
