Awesome stuff.

Yes, "Move to Usergroup, Except Banned Users" means that regular multiple registrants will still be registered and moved to the Prevention Usergroup, but those registrants that have one or more banned accounts will be completely disallowed from registration - they will receive an error message and no account will be created. "Disallow Registrants, Except Banned Users" is the opposite, where banned users will be rebanned and everyone else that tries to register a multiple account will be disallowed entirely.

Though remember, you must have the Banned Accounts Check enabled and the Primary Banned Usergroup set correctly if you want this modification to correctly identify banned users.
