Those webpages used to "test" blockers are frowned upon, see: https://x.com/gorhill/status/1583581072197312512

There are many reasons that sort of online tools are not able to reliably test a content blocker:

- Many content blockers are designed to fool pages to think no content blocker is installed

- Content blockers filter according to real, actual cases, not synthetic cases used in their tests
