I can exclude one IP address like eg 22.214.171.124 or an IP segment 94.228.34.*.
Does it work to exclude IP's with entries like 126.96.36.199* ?
Just wondering since 4D-DC just unleashed the magpie bot on my site with 700 "users" from the single IP mentioned above before I managed to stop it. The number of forum searching threads was growing all the time, noticed it at around 400 and it kept growing consuming more and more resources from the server...
The server did however stand up and served forum pages even if CPU was sky high constantly...
