IMO Y! and MSN (et al) both screw around with rDNS validation. I get hit with MSN ranges all day long, none of which are tagged as crawl. I too expect too much I guess. After all it's not really a standard that is scrutinized by any governing agency, and I don't want it to be. The more regulation, the more the "haves" get what they want and the "have nots" loose IMO.
