For those without a LinkedIn account (or a user who's simply not logged in), it appears somewhat random as to whether it will be possible to view profile pages - sometimes they load as expected, and other times a login screen with the blurred background is rendered instead (presumably to prompt the user to login).
I am curious as to the bases on which LinkedIn determines whether to display the actual profile page or the blurred version with login. I suspect it may be:
- based on IP (or IP range)
- based on repeat site views
- based on the device/browser you're viewing the site through (or user-agent)
- something else?
