Most games don't inform someone in advance with a warning that they're about to be banned. And how would Bungie inform people they've been banned if they've never played D2 on PC in the first place? That doesn't make any sense. They aren't scanning people's computers for known threats when people go to check out and purchase. There's 4 different places to buy the game that aren't run by Bungie. If anyone should be mad they were allowed to purchase they should be mad at the places they purchased from for not scanning their computers or asking them to verify whether they've got banned stuff on their computers. Bungie already gave out ample information and time about what things will get people banned and what is allowed. Anyone who got banned during the beta and assumed they could buy the game and play without still being banned is entirely their own fault for assuming.
