I noticed the VIN sequence #'s were replaced with xxxxx Are these numbers valuable to crooks and should be kept private?

I believe it's just a courtesy to the vehicle owners, even though your VIN is prominently displayed either on your dashboard, or, like NY, it's on your registration sticker in your windsheild.

I've seen it that way on cars listed on eBay, and other sites. For some reason people don't want that information shared. I'm not quite sure why, though.
