 look at the country wide proxy list that Wikipedia keeps for X-Forwarded-
 For style proxies - for example. Though I'm surprised - you don't have
 *any* data on carrier grade NAT IP ranges?
 > Nope. We do not have special treatment for groups of IP addresses other
 than Tor and only for Tor because of widespread complaints from Tor users.
 We have scores and data for individual IP addresses.

 OK - but for example - VPN services - or the Wikipedia X-Forwarded-For IP
 ranges - what data do you have on those? Do you see a threat score that is
 higher than really large Tor exit nodes used by millions of people
 (machines, bots, actual people, etc) daily?

 Sure, you're welcome - you can probably do neat metrics data comparisons
 too. Especially during censorship events, I expect you'll see interesting

 CloudFlare really just using Project Honeynet data here?
 > We are not just using Project Honeypot but it's an input. I'm using it
 here because all of us can look at their data and draw conclusions about
 any IP address or group of IP addresses.

 It is hard to address abuse if we cannot understand what that word means.
 I think Project Honeypot data is more of an art than a just process or
 even a fully explained science. If that is the only bit of data we'll see,
 I'm quite unhappy as it is effectively "trust us" as an answer.
