Something curious about facebook is, they let anyone access user profile/pages (or whatever it is called), so visitor can see the user profile picture and might be able to see other stuff. Facebook "protects" the privacy of the "visitor" because the user cannot see what visitors have visited their profiles. So, users have no privacy, but visitors have their privacy protected. Facebook should list "who" visited user profiles. I dont know why they dont do this already. And even more, they could somehow list what photos the visitor chose to see, how long visitor stayed on user profile, which 'full resolution pictures' visitor had downloaded. If they only saw thumbnails then no need to list, but if visitor made the effort to download all full resolution user pictures then the owner of those pictures should be able to see who has downloaded them. So this way, the user would be able to see how frequently visitor X, Y, Z has stayed on their profiles, and how many/which full res pictures they have downloaded/seen. If the user profile is not a person, but a store (or company snooping on you), then the store would be able to benefit from this data and send some message saying "We noticed you have been visiting us lately, and you seem to have a lot of intrest in product X. Do you want to know the price or make an offer?" Or, if the user is a person and has seen weird behaviour from weird users, then user would be able to take precautions. So in the end, the user profiles are public and have no privacy. But the visitors/consumer of other people profiles can snoop on other lifes and have their privacy protected because the page they visited is never able to know they have been visited by visitor X Ntimes.
