Nothing. It's the whole super-premeditated nature of the trolling that ticks me off. The ones that come in for a drive-by Trolling are really immature and impulsive. The one who have been waiting in the woodwork for +6 years to Troll is another level of liberal insanity altogether.
I agree, but, there is nothing we can do to prevent them from trolling. Unless they sign up with a really stupid screen name. Believe me, we see some incredibly stupid names. "Ihateconservatives" got the boot before he even got a chance to active his account. Then, the rocket scientist signed up with "Ihateconservatives2". And that's a mild name. You should see some of the profain names people try to get away with.
Could you give us an example?
