I get on average about a message every 3 months from recruiters looking for 'fresh meat'. What I think they're doing is they're looking at friends on facebook, then their networks and making the assumption that the person will have a gmail account, then guessing what it might be. Sometimes I'm cc'd into variants of potential spelling like firstname.lastname@gmail, flastname@gmail etc. but most of the time it's a bcc. If you bear in mind that my profile has a distinctly odd name which used to be a googlewhack and that most of my friends friends on facebook are in the UK and in the same industry (I use multiple profiles for multiple purposes).
