Great post rich. This is interesting. As glatt stated searches of you on FB by an employer or prospective employer is not new. Which is why I always recommended to people not to ever use your real name on FB. The reality is unless your friends also cop into your attempt to remain anonymous on FB you can be linked by pictures that others ID you in, or just casual conversations. It also brings up how effective some of the counter services are like Reputation Defender,

On a related note it is important that if you want to avoid easy data mining to never use the same alias on various social forums you participate in. I have seen people on this site do this to others here, search their Cellar name and find other sites they have posted on. Unless they get ahold of your IP, that is if you have a static IP address, it would be hard to find a trail if you change your name on each site. I never use the same name on any place I participate in.
