You got banned for using CFW on PSN, even when almost every PSN enabler and PSN enabled CFW told you there was a ban risk for doing so.
Oh, and you used a PSN account with stuff purchased on it.
Deal with it. Not to advocate warez, but if you really wanted to both pay for your stuff and CFW out the wazoo, grab a new-bootloader PS3 that can't be hacked yet, buy your content and run your discs on that, and on your CFW PS3, go crazy with backups, DLC activators, homebrew and whatnot.
With separate accounts, of course. Banned on the CFW PS3? No problemo - change MAC, spoof PSID, patch TargetID, use a new account.
