My console AND account got banned because I went online with it. I did NOT play games online, just was on PSN with a CFW console and they banned me.
So if you want to risk going online to play backups its always your own risk. They will ban you for the smallest thing. As I said I did nothing just have CFW installed and got banned.
It was 3.55CFW that I had installed. The one that if you flashed OFW3.55 there was no proof a CFW was installed at all and they banned me.
