I don't see why this COULDN'T happen. There are already list brokers out there who buy information from retail outlets (all those "member" programs that collect what you buy). They then combine them into master lists to sell In that same way if you search for Herpes and then are directed to a web site they'll have your IP and maybe a cookie. If you then go to another site and log in with your Facebook ID they'll have your IP, Name and Facebook ID. So all it would take is an industrious list broker to start combining that info like they already do with offline info (and in fact probably combine that with the offline info to get even more comprehensive lists)
