Anons. Those of us who are technically minded want to understand in more detail how we are all tracked on the web.

You might also wonder how the privacy settings on your browser actually work. For example if you set "Do No Track", are advertisers and domain owners required to honor it? No.

So every time you visit a webpage that has a Twitter icon, or a Facebook icon, or Reddit or Instagram or whatever icon, your browser makes a request to the site hosting that icon → twitter.com facebook.com or whatever → along with what site you were last visiting when the request is made. And a browser fingerprint can be obtained. That's a very crude rough description of what happens but essentially correct.

So even if you never visit the Facebook.com website directly, and don't have a Facebook account, if you have ever visited a site with a Facebook icon, chances are you browser has visited Facebook. Same with invisible transparent single-pixel gifs that your browser has to go fetch from some advertiser's site → these are invisible to you and they are SOLELY for tracking purposes. And very very common.
