this is a human operated scam. The guy's question came from reading this page Wallpaper groups: The 17 Wallpaper Groups.
He may not be a professional spammer. Might signed up with one of the spam programs to make a few bucks. See: Where Do Spammers Came From? (A Xah Story of Human Animals).
Why's he asking me question? Of course, ask in a nice way, most people are eager to answer. Then, he's got real interaction with real people. Then, spam detectors get confused.
