Psychologically
Trolls exist simply to get attention. They don't care what kind, just attention. Trolls especially love it when you get really angry, because they have accomplised their two goals
1. Attract attention
2. Make someone angry, thereore giving them more attention.
Usually this cycle repeats until the troll is banned or satisfied.
