The act of a mod on a forum deleting threads and banning members for no real reason.
Originated from General Discussion on GaiaOnline where a mod by the name of Soundblast went around deleting threads and handingout bans for the sake of it.
"Dude, did you see that? 5 of my threads just got deleted for no reason"
"Lol, you just got soundblasted"
"Man, soundblast is a cunt. He banned my account because of a stupid thread I made 5 months ago"
"Soundblast has gone mad with power"
