They probably can't, since it's an extension and thus uses the user's browser, IP, cookies etc (Adsense does use mouse tracking and other techniques that will likely flag these clicks as suspect, requiring additional analysis). Therein lies the problem. It appears to them as if someone is going and clicking on every ad, or is using an automated headless browser to click on ads. That can easily get you banned. Google doesn't care about who is doing it, they only know that it is happening on your site, and as a result will treat your site as a threat to the Adsense network.
