Anti-spam companies should not have affiliate programs. It's likely to result in actions that reduce trust in your authenticity. (I'm giving SpamArrest the benefit of the doubt, of course. They could have been the ones responsible for the spam piggy-back advertising. But it seems more likely an affiliate (the link was a redirect that made it hard to tell). After all, they're from "tech-savvy Seattle, WA, USA." Oh wait, "Brian Cartmell was the founder and CEO of eNIC..." Wasn't that the company that sent out all those deceiving direct mail promotions that looked like domain renewal invoices but were really'll-make-money-and-no-one-will-ever,-ever-go-there pitches? Or am I thinking of something else?)
