these laws are unenforceable due to the nature of social networking sites and programs.
first off, EVERY social network (be it Twitter, Facebook, and MMO's [yes, MMO's are a social network in that you interact with other people]) has a clause in their ToS that you cannot nor should not in any circumstances give out your password or account information, and that admins of said network will never ask you for it. This is because of two reasons, 1) It severely undermines network security and the security of the users. and 2) It is against the law in the US for anyone to access another persons account on social networking sites (I believe under the CFAA and by extension Patriot act).
