How do websites actually implement that?

  They can see what the inbound referrer is to their page.

  I don't know how WSJ does, but Press+, a vendor used by many local newspapers uses Local Storage to assign a GUID, and then they track the GUID. It's easily defeated.

  Checking the referrer header.

    Right, forgot about that. I wish something like this was rolled into AdBlock, but it'd be nice for viewing NYT and WSJ: https://chrome.google.com/webstore/detail/referer-control/hnkcfpcejkafcihlgbojoidoihckciin?hl=en https://chrome.google.com/webstore/detail/referer-control/hn...
