Wowee, Websites on the Internet using JavaScript and Tracking Pixels to Record Everything We Do! This is the first time I’m hearing about it (https://hn.algolia.com/?dateRange=all&page=0&prefix=false&qu...). I certainly don’t have any counter measures available to block these activities from happening on my computer (uBlock Origin and similar tools can block these requests). I wonder how common this is (An estimated 55% of all sites on the internet use Google Analytics)?
