I approve of these new measures. Good luck in the anti-spam arms race. It always boggles me that the spammers think that forcing themselves somewhere that they're explicitly not wanted will yield viable "customers". If someone kicked in your front door, tied you to a chair and stuffed a sock in your mouth, would you then feel inclined to buy anything from that person?

I have been a low activity lurker. Just looking at the pretty maps for the most part. Although I am also very slowly reading the various tutorials on this site. Perhaps I'll share some of my maps, but they're more examples of how to make crappy maps rather than how to make a map you'd want to show off!
