They're using Facebook Pixel for analytics, when the tracking code is ran by the website it's loaded from Facebook's servers who are able to correlate your logged in Facebook session to the request.

Facebook must be harvesting insane amounts of user activity data, most sites on the net have some sort of Facebook "like" script or something on them.

For some reason i feel that is so wrong..

They should have a button on the website you need to click to agree for them to be able to do stuff like this...
