Comment (by jgrahamc):

 To summarize:

 0. We fixed the bug that caused a new CAPTCHA to be served for a site when
 the circuit changes.

 1. We'll roll out the ability for any CloudFlare web site to whitelist Tor
 so that Tor users will not see CAPTCHAs within days.

 2. We've reproduced the "CAPTCHA loop" problem and have an engineer
 looking into what's happening.

 3. We are in contact with Google to see if they can help us with number 2.

 4. I've asked our head of Infosec to look into an alternative CAPTCHA
 provider. We had already done this in the past and concluded that
 switching to the latest reCAPTCHA was going to be 'better'. It looks like
 it has not made things better.
