To get your console id have Charles running with the ssl and all that stuff
Sign in and on charles you will see two new files
Click on https://auth.np.ac.playstation.net
And lastly auth
When you click auth, info should appear on the right click request and you should see your console id to copy it right click on auth and save request then open it and look for consoleid=0000000xxxxxxxxxxxxxxxxxxxxxxxxx00000000 000000000000000000000000
That's your console id to change it go to tools, rewrite and if you have it set up you should already see the stuff to edit the header so click on PS3 3.55 then you should see 2 boxes.
On the bottom box, click add, then where it says type make it body. make sure only request is selected. make the first value is your console id, example the first value would be consoleid=0000000123456789012345678901234500000000 000000000000000000000000
And the second on is the one you want it changed to and where it says "where" make sure request is only selected.
Example of the second value is consoleid=0000000987654321098765432109876500000000 000000000000000000000000
You can only change it to a valid console id, cannot be random or just left blank.
Apparently Sony bans the console ID and if you use charles and send a black console ID you can still sign in and since the console ID doesn't go to sony because you send a blank value they can't ban your number, also some people tried this that were banned from black ops and they were able to play again because thats how black ops had banned was by the console ID but I don't know if this works.. maybe someone that is already banned should try this and post their results.

If you are a victim and its a mistake, contact them and explain, they will let you back on again if your reasons are just. And like Barry said they don't allow anyone on the network without joining in some way, even if you quick connect your still in one way agreeing to their terms, like age and location, then it activates the PS3, so it knows were you live to give you local TV stuff and so on. In the process it has your IP address, and consoles information ready to trace back to your isp if needed.
But don't worry about the ISP side because 9 times out of 10 your isp will tell them where to get off, unless you've hacked them or terrorists etc. or until Sony enforce a court order on them.
Your ISP does not hand out user information to anyone, unless as I said they have a court order I believe, and then and only then its down to them how far their archives go back.
Well, the end of this will be a PSN account for each PS3 in the next firmware. No more multiple accounts, only one, with your e-mail and password attached to your ps3.
And that will blow that Cloud thing they were doing about taking your save files to your friend's house by entering your psn login and password in your friend's ps3.
Anyway, sony is screwed, one way will ban "innocent" consoles another way will remove another feature that is multiple account (but sony is very good removing things, hun ?) and that way will kill Cloud app.
