That was the iContact head anti-spam officer who killed the APS account. The comment was on the anti-spam blog Mainsleaze. And then APS was put on the Spamhaus DBL for a couple days:
Tom Mortimer of Spamhaus:
SBL listings are public record, Andrew. It’s quite alright with us if you name names, although we do appreciate the discretion on other issues. Speaking of which, there were some other issues than simple spam in this case. I can’t go into detail, but suffice it to say that this was most certainly a customer that no reasonable ESP or ISP would want on their network. :/
