Yes, I do. Because Facebook is a place where stupid people breed. Have you ever look at the comments on pages like WWE Memes? Those wrestling fans are beyond fucking Blue. If my family didn't add me on Facebook, I'd delete it.
Plus that whole thing where businesses and organizations can just call up Facebook and ask for your private information, despite your privacy settings. And I know for a fact that they do this because my friend in Indiana has experienced his school trying to take control of him. His school called his dad and told him that his son was skipping school that day because of a status he posted, when really he was injured on his bike the way to school that morning. Facebook can go fuck itself with a spiky metal dildo.
