you can go to the ps3, and then delete the user, is that what you want? Rep me

No I think He means how can he make it so people cant get on his account using other PS3's. And you cant do that. Just dont give out your Password and you are all good.

I dont understand what you mean?
The only way im thinking of is to personally delete your account of the ps3s that you dont want to be on. Or are you talking about gamesharing where you need to deactivate one ps3 system to download it again?
