Not really. If your account is permanently banned, then so is the person mastering the account. He/she is not allowed as per the forum rules to create another account, save for appealing on Meta, where the chances of recovering the original account are basically cero on plagiarism cases.

One may try to be all hush-hush about it, but eventually someone may find a link back to the banned account somewhere down the road, and then the ban will be triggered again without much contempt.
