Is this something I can implement on a channel level, or would it have to be implemented at server level?
Is there a cat in hells chance of anyone implementing it?

I can't say I'm all that surprised to learn that what seems simple to me is in fact much more difficult than is obvious.

The nicks are machine generated random words. The only really consistent feature is his use of TORs.
However it occurs to me that if I can devise a script to detect the character string "G-lined (AUTO  DNSBL listed" and then set a key on the channel for a period of say half an hour to several hours, this would limit his intrusions to a single event in that period, whilst resetting the channel to open (no key) until he next appears. Anyone got any advice or hints on this task?

After the pain and fuss involved in rounding up enough of our people and getting them registered to re-register the channel when we managed to let it lapse a while ago, I can't see this working! Plus there is the problem of a large pool of occasional visitors we don't want to exclude.

I haven't got a whois for him, just lots and lots of them for anonymous relays he has used.

Actually, I've gone one better and I am cautiously hopeful it will be successful.
I have contacted his mother. Although he is in his 30s, he has never held a job and lives at home with his mother!
