I really do find it hard to understand what these people get out of it. It sounds like they put a lot of work and effort into pursuing their bazar hobby. Some people call them Keyboard Warriors, but to my mind at least, a Warrior attacks you as is face to face. I would refer to these people as - Covert Keyboard Commandos. When a Commando attacks on a covert op, he wears camouflage, in a broader sense, changes his appearance / identity before he attacks.
All very sad. I hope legislation catches up with what has clearly become a major problem in modern life.
