I use a fake name, fake location, no friends, no uploads, no posts, no nothing. 90% of the time I use it for work to get a read out on the people I'm interacting with in person. The other 10% is Marketplace. Which is a pain because people think I'm an erek or something because of the anonymity.This is 100% why my FB profile is set to "posts visible to friends only" and I don't have Twitter.
