Ok, Let me put in my two cents worth on this can of worms I just opened.
As a carrier, I know that we should not and can not filter/censor/monitor
any content on our "pipes". This includes unsolicited emails,
pornography, whatever, but there comes a point where the amount time to
respond these issues that I can not perform the job I am paid to do. I
have a large network to maintain, I don't have time to worry about issues
except ones that directly effect how I run my network. But since I am the
contact listed for various networks, RA entries, etc, I always get brought
into the middle of the battle. So, I am not asking for a meeting to
form policy, I am asking for a meeting to know how other providers are
dealing with this problem without just dropping the emails of angry
recepients into the bit bucket, which is not an solution.
