Just when I thought that I'd seen the last of comment SPAM on my website after turning on TypeKey - I was surprised to find that my inbox was full of trackback notifications - 40 of em! Puzzled by this I logged into Movable Type, only to find that there is now Trackback SPAM!!!!! ARRRRRGGGHHHH!!!
Track back spam is invariably for fraudulent products. As I have said before, we need to start sending these con-artists to jail.
