You don't see their posts AT ALL? Or is it just constantly hidden?
-
I think it's almost like hiding threads. You can still view their posts/threads if you click "show hidden posts".
-
You don't see their replies/comments and their OP's are hidden when you are in the main forum view. Unless you muted with a reason other than "No Reason". In that case, if there are enough similar mutes, the member could end up being banned, in which case they're gone.

They're hidden by default. I just tried muting you to verify, I'll go unmute now.
