People are paranoid. Sony won't ban anything. That's the worst they can do right now. Atm: Sony in court for removing "OtherOS" firmware, which seems to have made it gotten more copies sold. They start ban people's console? Now that is hilarious. If you ask me, why woudl they even bother, even if they had some sort of Warden (that World of Warcraft) has to scan the memory for injected processes..
People get banned from Call of Duty, that's up to the developlers of that game, just as in Red Dead Redemption. If people start getting massive banned or whatever which sounds hilarious; I'll personally contribute to unlock them.
Isn't the masterkey out? Then what is a little firmware patch gonna do, when it was stated several of times that it cannot be easily patched that way. Free PSN, living off PSN store, in minus on sales, busy with all sort of news. Hey guys! This stuff is going to get our console in the trash!
