Post, don't post, doesn't matter. Your friends who do post will give enough information about you that not having an account wont matter. Nothing stops someone from tagging you in a photo. Nothing will stop people from posting "Hanging with XXX @ YYY". Putting 2 and 2 together: they now know who you are, types of places you visit, and what you look like. And you never made an account. After this your choices are: - get radical with friends about what they post about you - give in and use facebook - stop hanging out with your friends
