Well that do bring a pretty interesting question. I publish a message on my Facebook wall, can it then be kept on Facebook US database? It just like an e-mail, any recipient should be able to keep it, isn't it? Okay now I send my age, can they keep it? Why not? I send you my birth date by email, you can keep it, can't you? What's the limit, and how does it works? When I send an email, it's clear who's my recipient, so is that the limit? Recipients has to be clear? Then can a corporation be the recipient too?
