Hmm, maybe we have a business model here. I could easily enough make such spams not appear to users with over some threshold of karma, which the spammers presumably wouldn't have. Can you point me to the page with the offer?
I will email it though (you will need to register on a forum and make a few posts I think :) been a while since I joined) if you wish. Which email goes direct to you?
Though I suspect you were attempting to call a bluff ;) oops...
