What you are doing is gamesharing. This is not permitted under the "Terms of Service" for using the Playstation network and can lead to getting your account and/or console banned permanently.
It sounds like this has happened already, and there is no way to lift a ban. You should receive an e-mail from SONY within 48-72 hours.
