WOW,
One person who knows what they are talking about.
This guy is correct they do not ban a Mac Address, and the mac address cannot be seen past the router. Mac is only valid in LAN not WAN.
And yes it is the Console ID that gets banned.
Now for all the people that said you cannot change the mac address, you are kind of right. You can not change the mac address, but you can spoof. There are two easy ways but they are wastes of time since they do not ban the mac address.
(for the people who want to know how, Simply buy a game adapter, and it plugs to the ethernet hole on the ps3 then you hook up to your wireless and bam you are using the Mac Address of the game adapters Nic, OR you can simply download DD-WRT firmware for your router and then clone your pcs mac address. both wastes of time you will still be banned)
As far as the error code, It can mean either perma banned or month ban, usually a call to sony will clear it up. However in your case being a theif, you have probably gotten a perma ban.
Your best scenario is to trade/buy another ps3!
