Yep you are, you know it's not so bad, your account can say nothing other than your name and be completely private with nobody being able to even search for you but I get the whole paranoia thing. Had some cracking bargains off marketplace and offloaded plenty too, full of idiots obviously, like Gumtree but you know, good and bad in everything, every now and then you hit a good seller and it all works like a charm.
It's actually pretty good at seeing what's happening in your local area and finding out about stuff, actually there's plenty of positive things to be said about FB now I think of it, as well as all the negative.
