"Once I give out my email address, I can never take it back, and everyone gets the same priority ("unread") whether you are my mother or a salesman." This is true. But you don't have to give out your social network profile for anyone - requested or otherwise - to look you up, message you and potentially find out a whole bunch of stuff about you. (E.g today I found out - accidently, I was browsing around - that an ex-gf stills live at the address she used to, who her boyfriend is and the fact that they are, I think, about to move house. I am not "friends" with either of them and their public profiles are private.) Edit: this reminds me of an idea I had a while back: temporary email/contact addresses. Completely anonymous way of allowing people to contact you.
