Puri, back a few years ago my friend and I were playing an online video game. When you were shooting at other players online their screen name would light up over their head.
Well, being mischievous, I suggested a new tactic. We changed our screen name to " ." (just the period, not the quotation marks.) We deliberately set it off center. The tactic was banned shortly after by players, and shortly thereafter there was a server wouldn't even let you pick anything resembling it. :)
