Actually, Yes I am. If I attend an event, my friends and acquaintances will often upload pictures of me. I do not have a Facebook account, but they are known to operate shadow profiles.
And people say Facebook allows companies to upload their customer data to Facebook so they can be targeted through ads on FB, so it would be possible (in theory, not sure about the practice) that Facebook has things like your address and income level as well, for example if you ever filled a marketing survey.
