What's preventing this person from using a different IP/VPN or whatever it's called? If he's that desperate to come back sooner then he could probably mount that kind of challenge. Or would it be too hard for them to go under the radar? I'm not a techie so I have no idea how any of this works.
I have no idea about the techie stuff either, but even if he could circumvent that, his personality, mannerisms, and behavior are too obvious. Considering he's unable to control himself, he'd give away his identity rather quickly.
