Blocking IPs from a particular city?

[thetootall]

We have a troll in Tulsa, OK who will not go away. We keep banning her IPs and when they change she's back. She uses Sbcglobal and Cox, and she has registered about 20 names so far. Is there anything we can do, that's a more permanent fix?

Thanks!

setup in your .htaccess a rule to deny her by IP class and ban a full range its not likely they'll get a IP out of their class if its dynamic so do something like

Order allow,deny
Allow from all
deny from 24.186.123.*

The only problem is that our board is hosted on IIS6, and the IP addresses being used are in multiple subnets (some 15+)
