Comment (by cypherpunks):

 Please consider setting up both, IPv4 - & IPv6 only domain. To test them
 individually. As the exiting IP will be punished differently like
 another's IP but while it's the same exit, only different protocol.

 Also important can be the first seen date of a fingerprint. To group out
 if only "fresh' exit IPs can reaches it's destinations for a short period
 of time until they are burned with endless troll captcha.

 This will hopefully help to proof all the frustration and headache that
 cloudflaw is throughing against all Tor users on daily basis.

 For every UA not a browser, I guess >90 fail rates.
