Troll
Keywords: Online Go
A troll is in general an Internet phenomenon of someone hanging around on a (mostly interactive) site, with the sole purpose of provoking people into discussions, for the sake of discussion or even insult only. This phenomenon can be observed on Go Servers, especially in kibitzing high dan games, for there is a lot of attention to be drawn.
Trolls are often detectable for their lack of comment about the specific game, and their desire to lead discussion in unproductive directions, for example, the chess troll, who keeps comparing go to chess.
The book Get Strong At Trolling offers advice to prospective trolls.
