 captcha on POST would be a very basic and simple way to reduce the flood
 of upset users. Ensuring that a captcha is solved and not stuck in a 14 or
 15 solution loop is another issue - that may be a bug unsolvable by CF but
 rather needs to be addressed by Google. Another option, as I mentioned
 above, might be to stop a user before ever reaching a website that is
 going to ask them to run javascript and connect them between two very
 large end points (CF and Google).

 I'm not convinced about the R/O solution. Seems to me that Tor users would

 POST to a forum or similar. I'd much rather solve the abuse problem and
 make this go away completely. Also, the CAPTCHA-loop thing is an issue
 that needs to be addressed by us and Google.

 I still think the blinded tokens thing is going to be interesting to
 investigate because it would help anonymously prove that the User-Agent
