I just tested with Firefox and uBlock Origin in the stricter "medium mode" and got a score of 1%. So yeah, I don't think these test pages are that great.
Would you be supportive of an "adblock test page" that literally just reports if the adblocker is working correctly, rather than how good it is? Like maybe an EICAR-like rule that is added to EasyList that matches an element on that page?
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
