Can you sell something which is free to someone else? I guess that depends on how good a salesman you are.
Are you selling your facebook, twitter and google+ accounts alongside, as a complete package? Because it wouldn't be much use without those! And don't forget your user name and email, with the associated passwords..
Although, I can't imagine who would buy them!
Oh, I see! You want to sell yourself! Yes, I've heard there are people lurking around the net wanting your identity. Throw in your name, address, telephone number, bank account details, mother's maiden name, and so forth - I'm sure there will be lots of offers.
Somehow, I don't think Fanslave would want to be a part of such a scheme.
