I'd start with any of the 'contact us' links that are probably all over their website. You never know, they may have inadvertently started monitoring your websites, or your upstream provider might have signed themselves or you up. If it has something to do with your upstream provider, bring up the added bandwidth issue, and ask how that affects your monthly bill. I'm sure someone can simply stop these hits at the source. Failing that, look up the IP block and just block that range: $ whois -h whois.arin.net 65.194.51.165 UUNET Technologies, Inc. UUNET65 (NET-65-192-0-0-1) 65.192.0.0 - 65.223.255.255 Keynotes systems UU-65-194-51 (NET-65-194-51-0-1) 65.194.51.0 - 65.194.51.255 This is a pretty broad range, so you might want to start with a range you know redalert uses (.131-.165), then just expand it as you get new messages.
