I appreciate you looking out for hackers like this tinkerbell. Sadly we cannot ban just based off your demo alone, as we require and admin demo with the ban. BUT, you have provided up with enough details and a demo to show him suspect. All we can really do is put him on a watch list, and nail the sucker when he tries again.
Also if you need one of us quicker when he is on next time, just pop into IRC as we always have a few admins in there.
