>Assuming it actually works (which I'm not sure about),
Which it probably doesn't, given that it uses XHRs to "click" on ads, which is super detectable, and given the proliferation of ad fraud I'd assume all networks already filter out.
The other assumption here is that ad networks want to filter out all clicks but the most legitimate.
I don't think that's a very lucid assessment of how advertisers operate on the Internet. We all agree that they could take these steps. If AdNauseam doesn't look like outright fraud in the logs (which they don't if it's all distinct IPs and browsers), I don't think they want to cut it out from their revenue and viewer analytics.
Google wouldn't have gone out of their way to block it on Chrome if it didn't work.
