This project was started by Shiro (@shiromarieke@birdsite) and CryptoParty Berlin (@cryptopartybln@birdsite). Shiro handed over support to the greater internet in summer 2016.
It was a text list on okfn.org text pad: (https://pad.okfn.org/p/cloudflare-tor and https://pad.okfn.org/p/noncloudflare-torblocks)
However it was pointed out that this website itself was on cloudflare, and cloudflare actively blocked Tor users to access it.
So it was moved to systemli.org : ( https://pad.systemli.org/p/noncloudflare-torblocks ) and an onion service ( http://j7652k4sod2azfu6.onion/p/noncloudflare-torblocks , http://j7652k4sod2azfu6.onion/p/cloudflare-tor , http://j7652k4sod2azfu6.onion/p/cloudflare-philosophy )
These systemli pads needed to be updated once in every while (week? month?) or the whole list was scrubbed.
This happened a few times, and there were some attempts at vandalism up to and including june 2016
A fork was made during a multi-day outage at http://git.vola7ileiax4ueow.onion/fuckcloudflare/cloudflare-tor/ (new, not GitHub repo)
However vola7ileiax4ueow's git service went down, so it was moved to github
There used to also be a list of websites that were on cloudflare but are no longer. This list has been lost ( it was on https://pad.systemli.org/p/ex-cloudflare-tor )
