The screenshots below depict exactly what happened. In terms of photographic context, that might seem murky but I'll explain it. Villains want your camera gear to sell to buy drugs, hookers and so on. Facebook makes it easy for villains to find you and where you live. They're not all as stupid as the villain in the screenshots. Incidentally, they did apparently ring my friend's redundant Google Voice number from a number identified as (260) 702-2273 which comes up as a Verizon cellphone number.
My recommendation - stay as far away from Facebook as you possibly can. Avoiding Bank of America is also a good idea as I recently noticed they were adding $12 a month charges onto a positive balance.
