Well, let me see. As extreme cases, Gunman was actually removed if I remember correctly. I haven't seen Socrates lately, but he usually shut up as soon as someone pointed out he was on the wrong page of his thesaurus.
In normal cases such as headon whines, thisplaneisporked/HTC conspiracy rants, vultch whines, gangbang whines, chuteshooter whines, ack whines, planetheotherguyflies whines, TnB whines, BnZ whines, warp whines and cheater whines, pointing out an individual is acting like an bellybutton is usually sufficient.
To the relevence of the post, ignoring my statement for a moment that the boards were not as bad, much of the attitude carries over into the main arena. A post stating that aces high is 100% nonsense would in my humble opinion fall into that category. Though I do agree that Mandoble at least keeps it to the boards as far as I have seen.
