Don't know if the issue is already through here..., but:

Isn't it possible that CloudFlare's captchas allow fingerprinting of
tor users (looking at typical errors, re-captchas / timing), given that
everybody of us solves them over and over again? Not necessarly done by
CloudFlare itself, but by whoever listens to enough of the traffic?

best,
amharic.
