Yes, and we block tor as well for this reason. It's mainly used by spammers and trolls on our site. Unfortunately tor doesn't/can't do anything about its spam problem (unlike hidemyass who will kick off trolls). This means it's pretty much useless for anyone wanting to use it legitimately because eventually some asshole will get you blocked.
