Ad Blocker Test – Check If Your Ad Blocker Works
This ad blocker score test has users arguing whether it’s busted or brutally honest
TLDR: AdBlockTest lets people check how well their ad blocker works, but the site itself warns some browser setups can confuse the results. That warning became the real story, with commenters split between victory posts, low-score panic, and accusations that the whole thing is misleading.
A simple website that promises to tell you whether your ad blocker works has accidentally launched a full-on comment section identity crisis. The tool, AdBlockTest, gives users a score, a color-coded ball, and a compatibility table explaining that results can get weird depending on your browser, blocker, and settings. In plain English: the test says it measures how much junk gets stopped, but even the creator warns that some setups can confuse the system, and a low score does not automatically mean you’re unprotected.
That disclaimer did not stop the crowd from going feral. One user stared at a miserable 7% blocked result and basically said, “Excuse me? I barely see ads anywhere.” Another got 0% with Firefox and uBlock Origin, while their blocker proudly claimed it had already swatted 102 items. That sparked the biggest hot take of the thread: is the test broken, or are people misunderstanding what it actually measures? The loudest skeptics called the numbers nonsense, while the victory-lap squad rolled in with brag posts like “100% thanks to NextDNS and AdGuard.”
The funniest mini-drama came from a commenter who declared the whole thing busted, then returned with the classic walk-back edit after spotting the warning hidden below the fold. That turned the mood from outrage to sitcom: part bug hunt, part humble pie, part nerd Olympics. The vibe is clear: people love a score, hate when the score insults them, and absolutely will fight about it in public.
