Apparently unsubscribe requests mean nothing. I got yet another spam from Marky Mark today, this time through FeedBlitz. Now if you recall, he used FeedBlitz back in June to send another round of spam. Rather than have his account terminated for violating the ToS, he decided to commit seppuku. I guess that was so he could crawl back under a rock until they forgot about him, then go sign up again.
Just like last time, you should forward those unwanted messages to firstname.lastname@example.org to complain about being forcibly subscribed to his list.
