Rodney,
You said "I see something every couple of months that I can track back to NANOG, or ARIN."
I would hardly call this a flood. But my point is that most people posting to NANOG, being technical people, respond to notifications that they are spamming. Your example email illustrates this perfectly. Sometimes they're ignorant and don't realize they're spamming. If they're persistent they get removed from the list (I don't think that has had to happen for several years).
The remaining spammers are easily caught by filters, as you can plainly see.
I don't see your need for urgency, and you still haven't said what you propose as a better arrangement. I made my suggestion. What's yours?
I'm one of 10,000. I assume others see as many as I do (I have no idea how many get caught in my filters).
I don't recall calling this a flood. Did I? And I don't believe he is on the list so there's no way to "remove" him. I think the list does a good job over time "training" subscribers.
But I did say that if others don't respond to spammers to this list from vendors, it will become a problem. The list is fertile ground. And I'm not sure that Sterns response indicates any awareness. He admitted he used the 1,300 person attendee list as a prospecting tool.
So all that I am suggesting is that others take the time to respond to spam from vendors (as I did) rather than ignoring it (just hitting delete doesn't work out in the long run). I have to assume that after a reasonable number of people do complain to his company, they'll learn. And others on the list who are tempted, change their minds. I don't think the list itself per se suffers from a spam problem - although my 3 emails probably qualify as too much noise already. But it is vendors who use the list to prospect who should be discouraged.
Btw I have no doubt that rogue salesmen from my companies over the years have tried it once. When I find out about it, I do kick butts.
I'm hoping that this discussion is enough to get Calient to rethink their strategy. For crying out loud, the guy is a VP in their company. What kind of example is that?
I'll end my public noise here
