I line up my team in a crowded city, set down 2 walls of totems, go ghost wolf form and /dance. Usualy some people come with comments like "omg fucking retard has no life". Then I start a polite conversation which provokes them into nerd rage and more insults.
... and then I report them to a GM, add to friends and enjoy watching their names as offline for next few days.
Less people playing - less server lag!
