Website is rejecting Tor visitor

List name Description
/fqdn/attd.txt Block Tor access Split files, Everything (FQDN) Does NOT block Tor access Domain and Comment

  • Some news websites are lying to Tor users. You can read their website if you are not using Tor nor VPN. If you visit their website over Tor, they just say "Sorry, article not found".

  • Imunify360 is not so intelligent because it is blocking real human.

  • Some famous mail subscription service and some ISP websites are displaying "Maintenance" page if you visit them over Tor.

How can you trust their sites if they are not treating everyone equally?

About "Anti-Tor FQDN list" (attd*.txt)
   ---> denied/bullied Tor visitor.

   ---> subdomain of is denied Tor user.
   * unique hostname will be masked as "?" for privacy reason
   ---> base domain denied/harassed/challenged human who're using Tor.

If your website is on this list, you better talk with your network administrator.

But my website X no longer blocking Tor users!

Are you sure? There are two ways to remove yourself. First option is just remove it from the list and create a pull request. Second option is wait 1 year. Our system will revisit your website as a Tor user.

If you're not blocking Tor users, you will be removed automatically.

  • If your website is using Cloudflare
  • There's a higher chance that we receive rejection webpage from Cloudflare. Do not use cloudflare.

How to setup git

This procedure will give you a stop_cloudflare fork with a privacy-respecting configuration to do pushes with SSH over Tor using"CDB"). Below procedure is designed for Linux. The first step covers Windows too, but these instructions probably need more adaptations for Windows and other platforms.

  • Linux: aptitude install git tor ssh
  • Windows: Download PortableGit from Github & run git-bash.exe
  1. Install Git, SSH(Not Windows), and Tor (if you haven't already)
  2. Create a account (username "snowden" will be used for this example)
  • NOTICE: Codeberg is blocking temporary email services and some minor email providers(not temporary email).
  1. Create an SSH key pair $ ssh-keygen -t rsa -N '' -C 'snowden at codeberg' -f "$HOME"/.ssh/id_rsa_codeberg-snowden
  2. Edit $HOME/.ssh/config:
         ForwardX11   no
         ProxyCommand connect -4 -S $(tor-resolve %h %p
    host codeberg-snowden
         IdentityFile /home/user/.ssh/id_rsa_codeberg-snowden
  1. copy "$HOME"/.ssh/ to clipboard
  2. > settings > SSH/GPG Keys > add key (paste from clipboard)
  3. $ firefox
  4. fork it (top right corner)
  5. go to the directory you want the project to be rooted in (hereafter we'll call it $project_root).
  6. anonymously download your fork: $ git clone git@codeberg-snowden:crimeflare/cloudflare-tor.git
  7. edit $project_root/cloudflare-tor/.git/config to include the account name and email address that will be on every commit, as well as the URL:
        email =
        name = snowden
[remote "origin"]
        url = git@codeberg-snowden:snowden/cloudflare-tor.git
     	fetch = +refs/heads/*:refs/remotes/origin/*
[remote "upstream"]
        url = git@codeberg-snowden:crimeflare/cloudflare-tor.git
     	fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
	remote = origin
	merge = refs/heads/master
  1. make your first change
  2. (from $project_root) $ git add . -u -n
  3. check that the files listed are what you changed and intend to push upstream
  4. if yes: $ git add . -u
  5. $ git commit -m 'description of first change'
  6. $ git push origin master
  7. $ firefox
  8. make a new pull request


Whenever git operates on the cloudflare-tor project, all connections to codeberg are automatically over Tor with this configuration (because the url in .git/config references the virtual host codeberg-snowden in ~/.ssh/config).

About Cloudflare base domain list

Our mission is clear - stay away from Cloudflare.

If the is cloudflared, we add to the database. ( is the sub-domain of Only the owner of can create sub-domain)

Even if is not behind cloudflare we will raise a warning, because the base domain is cloudflare user.

The owner of can enable Cloudflare to at any time without user's notice. It can be done from webpage or hitting Cloudflare API. The owner is supporting Cloudflare and this is severe security risk.

Until the owner completely stop using Cloudflare service for, we do not remove from the database.

There is no exception.


$ getweb --headonly

cf-cache-status: HIT
expect-ct: max-age=604800, report-uri=""
alt-svc: h2="cflare******.onion:443"; ma=86400; persist=1
server: cloudflare

If the owner moved away from cloudflare completely, you are welcome to add to the "ex_cloudflare_users.txt" - after checking with online tool below.

  1. Open "Is MITM?" webpage.

  2. Input and click Scan.

  3. Click test for detailed scan.

  4. If you got ---Finish---, the domain might stopped using Cloudflare. We'll investigate and remove it - or not.

  • wait some days and scan again to see whether the domain is removed

Only a few Cloudflare user leave Cloudflare. False positive is uncommon.

"Cloudflare is not an option."
