QUESTION about ps3 banns

so like the title says i want to hack on ps3 but can i get banned 4 hacking and how if i am banned my howle ps3 is banned or just my account?
so i could do a fake account to hack ?

Try to use proper grammar when you're asking a question...Anyways;

Sony can band your whole PS3 if they want to, or they could ban just your account. It depends on what you're hacking. If you're talking about like your MW2 rank, then they'll probably just ban your account.
