Trolling a Troll
Good luck with that. The act of double trolling is a dark art known by few.

Defeating a Troll
All trolls are human, and are thus no different from you and me. They all have a weak spot. You just have to find it. Some say you have to alt + f4 them to death, some say you must kill them with fire. Some will even CAST MAGIC MISSILE to get rid of large troll infestations. Banning them gets rid of the problem. Usually. One must be careful when banning a troll. All personal information ever made public in front of a troll is a death wish. When banning a troll, one must be gentle : too harsh and the troll will raise a little troll family outside of your IP Mask, and soon have a troll community, then a troll city, then a troll nation AND THEN A TROLL ARMADA. Much like the bear cavalry, a force this tremendous is unstoppable. Soon they shall rush upon you like rednecks rush to a country fair.
