Was leaving a comment about the Mario Batali rip-off story and it required me to sign up for Facebook. Figured no big deal, just an email address and I can leave comments. Somehow it snoops through your address book, and any name even close pops up wanting to be your friend. I have since gotten hundreds of emails and dozens of messages on my phone. How do I get off Facebook. I'm probably a little panicked so am not reading the site as carefully as I should, but I can't find a way to get out of it. Thanks in advance for any advice.
