Challenge: Open up your favorite website (not HN :D) and watch the XHR's and network calls in your browser's devtools. How many of those are for the same origin? How many of those are ad calls being blocked by your extension (which also has access to your data)? How many of them are calls for a single pixel gif? Some javascript? favicon.ico? Do some spelunking on WHOIS for each of those domains. All it takes is one of them to proxy the headers. Proxy the headers and check if ad was served by looking at logs of both ad request and page request, if no ad request was found, require them to disable adblocker...
