Correct me if I'm wrong, but a lot of buyers (end users) get the info from the whois record. A prime example is the recent sale of TGN.com for 75G's. I happen to know the person who sold it, and the info in the whois record is how the buyer got in touch with the seller. I do understand that a lot of people don't want that info out there, but this is general info that anybody could find out with little effort. It's not like you are giving out your SIC number, or your CC number etc. Address, tele number, no big deal, I think.
