I have a friend who likes to visit blackjack sites. From time to time, some strange person will start a fight with himself, just to stir up trouble. By this I mean that he logs on under more than one name, making inflammatory statements and creating the impression that a real schemozzle is occurring. Apparently he hopes to sucker other people into the fight so he can sneer at their emotions.

When this happens, the site posts a notice saying that it has been determined that So-and-so and Who-knows and What-dya-callit are all the same person, and that the thread is being stopped. Sounds fair to me. The troublemaker has no right to take advantage of other people's time and equipment.
