Another reason to block javascript from your browser. I find myself leaning more and more towards only unblocking js for very very select few trusted sites.

This is from early 2017 so I'm sure it's circulated around.

If anyone is looking for a solution, I have high regards for the guy running treaty.io. No relation, I'm simply a very happy customer: I drop in his library (effortless installation) for my clients fighting transaction card fraud.

Am I missing something here? The website states that it will "Identify devices across browsers and websites — without cookies." When visiting the site in Chrome it calculated a unique device ID for me. Out of curiosity, I then visited the site using Firefox. The calculated device ID was different.

Why is this a service?
