I've got a few on ignore.
I'll give someone a lot of leeway but it they just post a continuous stream of drivel, never posting anything remotely interesting as a discussion topic, always taking cheapshots at folks, routinely writing in a snide, supercilious manner... well, that's what ignore is all about.
It makes threads so much easier and faster to read if you clear the chaff out of the way first.
Like this thread for example.
