A few weeks ago I was looking up public profiles on LinkedIn and I noticed what I interpreted to be some network-side fingerprinting of some kind. The first couple profiles came up, but from that point I was only served a sign up page. It didn't matter if I changed browsers or spawned new incognito sessions.

possibly just filtering based on your IP?

That crossed my mind, but it'd mean they'd be willing to lock out large networks behind a NAT. I was wondering if there's something more sophisticated available.

100% they are willing to lock out NAT networks, have been subject to this more than once browsing normally.

Also, they are just locking out users that aren't signed in. If a user has a login, they are probably much more likely to err on the side of caution before locking down access in some way.

you can only view a few profiles at a time, and changing to incognito window will do the same.
