Comment (by arthuredelstein):

 Maybe CloudFlare could be persuaded to use CAPTCHAs more precisely?

 That is, present a CAPTCHA only when:
 1. the server owner has specifically requested that CAPTCHAs be used
 2. the server is actively under DoS attack, and
 3. the client's IP address is currently a source of the DoS.

 I think it's hugely overkill to show CAPTCHAs all the time to all Tor
 users for every CloudFlare site. It's also unreasonable to maintain a
 "reputation" for a Tor exit node.

 On top of this, Google's reCAPTCHA is buggy and frequently impossible to
 solve. Has CloudFlare considered other CAPTCHAs, or discussed reCAPTCHA's
 problems with Google?
