So you IP ban them then it they carry on after that you tell their ISP who will do something which, in Flynn's case, would mean he'd get cut off.

He does get IP banned. Issue is hardly anyone has a static IP address so give it a few days and he can get back on. Don't worry though, i don't think he will be back now

Hence the next step I suggested

Normally they don't give a shit and they would just pass it on to the police who would normally do sod all because of lack of evidence etc.
As i said though, its dealt with now
