>Australian internet security blogger Nik Cubrilovic first discovered that Facebook was apparently tracking users’ web browsing after they logged off in 2011

After reading that (in 2011) I decided to block all third-party cookies.

The other side is not stupid, there are far better ways to track users than cookies, and blocking them takes a lot of effort.

What better ways than cookies is there to track users ? AFAIK, it's the most unique fingerprint you can get of a user. Everything else is probably going to be a lot less precise.

I think browser fingerprints are quite a reliable way of tracking.

Sure, 'quite reliable' beats 'unique' every time!

[braythwayt]

Unique becomes unreliable the moment users delete their cookies.

[tinus_hn]

Which they of course do much more often than change one of the finicky parameters that constitute these unique fingerprints (which in reality tend to not be unique to begin with)

You can get unique through things other than cookies. Like abusing ETAGS/If-Modified-Since.

Thanks, is this done for advertisement purposes (selling data)?
