The possibility of rescuing hellbanned users is interesting. But "banned permanently" is possible only for usernames, not actual users, and certainly isn't a punishment more severe than hellbanning. A "permanently-banned" user will presumably be notified they've been banned immediately... so instead of wasting time making posts that are hidden, they'll switch IP addresses and grab a new username immediately. And presumably they'll get some posts seen by normal readers before the new username is banned as well, unfortunately.
