Wouldn’t geo-locating the client request, and selecting the CAPTCHA challenge accordingly, be a way to mitigate this risk? i.e. for client requests from the US, it’s “Please select all the images of crosswalks” with photos of American crosswalks, but for Commonwealth countries it’s “Please select all the images of zebra crossings”. Admittedly there are flaws in this plan, such as when someone uses a VPN to obfuscate their IP address, but surely it would be a net gain?
