I never ignore or block anyone on any Internet forum that I use. Why? Because people should be able to say what they want and it also makes for good discussion/debate. Heck, even if someone is being rude, racist, trolling, etc. I don't think they should be banned or moderated. Everyone has a right to be an a-hole and everyone else has the right be able to spot the a-hole in the crowd.
