Well, I still continue to get email spam from Epicurious every single day. They didn't honor the unsubscribe request, and I've escalated to filing complaints with the FCC and FTC.
Yesterday the FCC responding to me, saying that they are looking into my complaint, yay!
However, my prediction is that Epicurious will tell the FCC "oops, technical glitch, sorry," take me off their mailing list but continue to spam everyone else who didn't complain to the FCC. But the FCC has a newly-developed spine during Obama's second term, so we'll see how this plays out.
There are also a few more cards to play if I get no love from the FCC complaint. But I'm giving it a week or so before I keep at it. There's also the possibility that they could do something lame or stupid and draw attention to the issue.
