If the IP addresses, hostnames, or domain names are not yours, why would you even bother responding? IANAL, I don't think it's your responsibility to direct them to the correct place. Consider an auto-responder directing them to the DMCA page of your corporate website. matthew black california state university, long beach -----Original Message----- From: NANOG [mailto:nanog-bounces@nanog.org] On Behalf Of Baldur Norddahl Sent: Friday, October 09, 2015 1:00 PM To: nanog@nanog.org Subject: IP-Echelon Compliance Hi I am sure all of you know of these guys. But what do you do when they keep spamming your abuse address with reports for illegal downloads from IP-addresses that are in no way related to our business? I tried contacting them. And was told repeatedly that I had to update whois information if I want the reports to be sent to another address. How I do that for IP-ranges that are not mine is a good question. Besides the whois information for said IP-ranges already have valid abuse information and it is not our email address. Do I just block them for spamming? Regards, Baldur
