Pliable posters use the "Ignore User" forum feature.

Personally, I'd like a feature where instead of just not displaying posts from x users, make them display, but hide them as though they were deleted with a 'hidden: User on Ignore' message. Then if I really want to see what they say, i can just click to display!

Man that's a good idea. Sometimes I astound myself.

That's what it does now. :P

I actually read and reply to a couple of the people on my ignore list in threads outside of General Chat and EoEO and stuff because they're fine when they're not talking about themselves.
