Trying to circumvent a ban is the equivalent to trying to break out of jail (to me).
You're privileges to use PSN have been removed (like you're freedom is when you are arrested), and therefore you have to pay the price (banned = no more online, arrested = no more freedom).
If you received a ban, ultimately you will deserve it. Just like there are people who get arrested improperly, people are banned improperly. Though I am willing to bet a lot of these bans are justified because you're doing something wrong/against the law (Sony's law regarding PSN).
Not trying to be a negative Nancy or anything but... your cards are dealt and you have to use them wisely.
Help, im stuck!
