I just installed AVH and it worked great, I tested blacklisting an IP and it was blocked, and Counterize didn't even know it tried to access!
I have a request: IP range! I was already spammed by somebody that was using a whole network, alternating IPs around it. In Project Honey Spot ppl also noted it and found out the network owner, but we can't anything other than blocking the whole subnet.
And I miss this feature on AVH, add a single line and block a whole IP range at once! :D
