a super cool map that shows waterflows and rivers all around the world. When I looked closely, I could see via the browser extension privacy badger (https://privacybadger.org/) that there is a tracker (analytics.ahrefs.com) on the website which is unnecessary I think. Also ublock origin (https://ublockorigin.com/) blocked gc.zgo.at which seems to be a open source web analytics platform (https://pkg.go.dev/zgo.at/goatcounter/v2#section-readme). Maybe 3/5 blocks because of that.
