You get warned for bad mouthing
ANY GAME COMPANY Not just EA, I've seen people bad mouth 2K Sports and get banned.
I really don't care about how "accurate" Madden, they got 8 out of the last 10 Super Bowls right, congrats. I actually try to have fun with the game. Funny thing about Super Bowl predictions: I've gotten 6 of the last 7 Super Bowls right.
