I have a person contacting all my clients trying to solicite business (another hosting company), I guess they must be getting my domain lists from whois.sc. Instead of being forced to pay the place that is causing me the trouble by providing reverse lookups on my ips (whois.sc) someone had mentioned before that you can block them through your iptables.. anyone have that info on the ip,etc? I did a quick search and didnt locate it
