Then I had but to send another abuse complaint to LACNIC (abuse@lacnic.net). The only answer I got is an automatic message saying that it's not their responsibility at LACNIC to investigate abuse issues.
Yes. This is one of the reasons I got out of abuse-fighting: the upper levels of Internet governance (RIRs, domain registrars, and IANA/ICANN) are exercising authority without accepting the responsibility that goes with it. You're not likely to get anywhere. No such system is sustainable, of course, but the net is robust enough that it's taking quite a while for the abuses to grow to the point where the system collapses from them. (It's coming, though. I recently dropped by a university I used to work for, and someone who goes back even farther than I do there says there are now people trying to get them to build a completely private (totally off the net) email system so they'll have usable internal email.) /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mouse@rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
