Yes, plenty of people disrespecting the hosts kept throwing melee up every now and then, despite them stating "melee free" before the tournament, as well as during. Oddly enough... It was the same 4-5 people too... Over and over lol.
I don't understand what you mean when saying, "what are you trying to prove"? Stating there was no melee at a brawl tournament? Why not throw up some Mortal Kombat II too =p? Or we could go to a Guitar Hero tournament... And throw up Guitar Freaks in the corner? Wait... That doesn't make sense? It's a Guitar Hero tournament... Not another game.
Fun times =D
