Corpuses may be uniqued and perhaps stripped out of some newsletters, bounces etc redundant stuff. So certain rules might be exaggerated, but it just might be in the direction of mail that really matters. I only have to look at my mail logs from today, and I see dozen of legimate RDNS_NONE hits originating from real people. I'm happy to greylist it at MTA, but not block directly. As said, it's a site policy. Some people use high FP BLs also happily. Many people might not report FPs for one reason or another, but it doesn't mean they don't exist.. I like to be on the safe side.
