I half suspect it’s users who are not logged in and the content is just generalized for the area they are connecting from. Or perhaps even through using a VPN and showing content associated with the IP you happen to be using, as others would have probably been using that IP as well and I can see by logging out myself that it still shows things it would show me when logged in so I have no doubt they also just keep track of what content is being viewed by anyone connecting from a particular IP address.
