The box has made browsing using TOR insufferable! It fusses and makes me click storefronts and traffic lights until I run out of patience and close out of whatever webpage I was trying to visit. I assume it has to do with a lack of Google cookies on the browser, essentially punishing me for trying to protect my privacy.

When trying to detect ad fraud, one problematic scenario is that of replay attacks. It's basically when a scammer records human behavior on a site, and then replays a mix of actual their sessions to fraudulently click an ad.

The Quora answer is interesting but it's not clear to me whether the "I'm not a robot" box cannot be defeated in a similar manner.

Those images are infuriating!

Click all boxes with traffic lights. Ok, well, this one box just barely contains the bottom right corner of the traffic light. Click. Nope, that little corner didn't count. Try again. Ok, well on this one, the right side of the traffic light is only barely over the line, so I won't click it. Nope, that sliver of the light mattered this time. MF!

This might surprise you, but it actually has to do with what traffic coming out of TOR looks like. Well in excess of 90% of traffic coming out of TOR is spam, bots, malicious, or some combination!

Google isn't going out of their way to punish you for trying to protect your privacy. They're trying to stop unwanted traffic. By unfortunate happenstance, you appear to be disguising yourself in the exact same way a shocking amount of bad traffic is.

The worst thing is that Cloudfare is using ReCaptcha, and it's everywhere. The internet is broken at this point.

It seems like they make that hard by mixing semi-random elements that are different each time, like user interaction data, with the user's browser fingerprint and location. This seems to be why they go to such lengths to obfuscate the algorithm they use to combine these elements. If the pseudorandom and the fixed elements were easy to separate it would make replay attacks much more feasible.
