As old as this topic is, I've had to bring it back up because... drum roll... after two years without him... he's back.
New e-mail address. I accepted the add without even thinking. In fact, I'd forgotton about it until his first words were ''[my IP address] then Sarah Green Eyes''
He knows my IP. how's he doing that?
The e-mail address he's using now is firstname.lastname@example.org
He's used this name before, just not this exact e-mail address.
I'm not that bothered about it anymore, its just plane WEIRD.
