Which websites featured on the Federation have the worst privacy?


My last post highlighted how ticking the OEmbed box to add a website picture to a post can compromise Federation users if it contains a tracker.

I also mentioned tools, like Disconnect, we could use to detect websites which track their users. In this post I reveal some of the most popular reference websites on the Federation with low privacy and high tracking rates.

I believe Federation users should consider not embedding, or at least warning their readers about the surveillance techniques carried out by these sites.

A Princeton University study identified almost a million websites that track their users. Here are just 5 examples of websites whose stories are commonly quoted on the Federation:

Operating systems – can we make them private?

How can Federation users post more safely?


You know how it goes. We find a great story online and we want to share it with our supporters or feature it in our feed with appropriate hashtags for maximum reach.

But do we check the website featuring the story for privacy before we post?

When we embed a link by selecting the OEmbed box (often ticked by default) this displays an image or video on our post from the website we’ve featured.




They may look cool, but these images can contain beacons or other trackers. Embedded trackers also load into the browsers of any user who scrolls down the public feeds.

Beginning with the principles of the Stirling engine, SoundEnergy's THEAC thermal acoustic engine takes heat – either industrial waste heat or solar heat – and turns it into powerful cooling without requiring any other power source. This completely renewable technology could prove highly disruptive.

CHROME
1. Click on Chrome’s menu and select the cog symbol – SETTINGS
2. Click the SHOW ADVANCED SETTINGS link at the bottom. Don’t be afraid of the ‘advanced’ implication, this has been worded to scare off timid sheep from reclaiming their privacy.
3. Click the CONTENT SETTINGS button under PRIVACY. While we’re here, consider unchecking the boxes urging us to use web services to ‘resolve navigational errors’ or ‘prediction services’ to auto complete our searches. This is just more telemetry.
4. Scroll down to the LOCATION section and select DO NOT ALLOW ANY SITE TO TRACK YOUR PHYSICAL LOCATION.

This is a comment I recently made, that I decided to post as a post.
I remember many years ago, when I purchased a “Universal Remote Control.” Disappointingly, it did not allow me to remotely control the universe. (But then, is it really possible, in principle, to be remote from the universe?)

When my roommate began to annoy me, I pointed the device at him and pressed “Mute,” but it didn’t work. What a disapp
