I'd love the ability to configure a list of rejected IPs, such that:
a) IPs in the reject list do not appear in the host catcher
b) Connections are not accepted from IPs in the reject list
c) Search results from IPs in the reject list do not appear when performing a search
d) Optionally, an IP address which generates a spam/flood ban would also be temporarily added to the rejected IP list (putting not only that term, but that client in the "time-out corner" until they can behave better). I guess there are potential security issues here, someone could spoof a spam flood from a legitimate user's IP, etc.
Just a wish list
