Maybe a bug-me-not that uses a VPN for a consistent IP and sends a spoofed user-agent for added uniformity would be an improvement.
Additionally, each time the account is deactivated, the service time-bans the users who most recently were assigned the deactivated account (suspected to be Facebook's security team) for 6 hours, sends all other users the credentials to a new auto-created account, and looks for repeat presence of IPs in the time-banned group to be perma-banned.
