  1. How to detect Cloudflare

There are many ways to detect it:

  • These add-ons will help your Cloudflare collection.
  • Visit a website via Tor or VPN, and you will be greeted by "Attention Required! Cloudflare" webpage.
  • Use "Is MITM?" webpage.
  • Dig "NS record" of the domain.
emsisoft.com.		21599	IN	NS	bella.ns.cloudflare.com.
emsisoft.com.		21599	IN	NS	dom.ns.cloudflare.com.

IMPORTANT: Please add only "Base Domain"

    if "community.example.com" is using Cloudflare
        add "example.com"

    if "www.example.co.uk" is using Cloudflare
        add "example.co.uk"

    if "example.net" is using Cloudflare

  1. If the website no longer using Cloudflare, remove it from /split/ list and add to "ex_cloudflare_users.txt".

Website is NOT using Cloudflare (& blocking you)

Anti-Tor users (formerly "TorBlocker Hall of Shame Part I") | List Directory

List name Description
/cidr_data/?.txt other CDN IPv4 CIDR files
list_othercdn_domain.txt domains behind these CDN (Not Cloudflare)
list_http_error.txt Websites that instantly and unconditionally deny service to Tor visitors by returning an HTTP error. HTTP 403 is the most common but this list catalogs all HTTP responses that entail DoS (i.e. not HTTP 200). File format is: <FQDN> <http error code>
list_customerror.txt Custom error message renders for Tor visitors generally without HTTP error.
list_other.txt Any other form of tor-hostility or mistreatment. This includes sites somewhat functional for Tor users to some extent but sneaky and unexpected adverse retalitory actions are taken against Tor visitors.
list_formerly_tor-hostile.txt was previously on one of the above tor-hostile lists

Above is how Siteground-hosted(INAP) sites often appear to Tor visitors when timeouts/tarpitting doesn't occur. If you see this please update list_othercdn_domain.txt. (CDN ID: Z7)

list_othercdn_domain.txt


{domain} {CDN code}

{CDN code}:
'amazon.txt':'Z1'
'akamai.txt':'Z2'
'imperva.txt':'Z4'
'google.txt':'Z5'
'microsoft.txt':'Z6'
'inap.txt':'Z7'
'sucuri.txt':'Z8'
IMPORTANT: Please add only "FQDN" or "FQDN[space](comment here)"

    if "community.example.com" is blocking Tor
        add "community.example.com"

    if "example.co.uk" is blocking Tor
        add "example.co.uk Error message: Anonymous not allowed"

Some websites use other companies with the CloudFlare business model.

This is a collection of websites that ban Tor exits, other than through Cloudflare(e.g. showing access denied pages, systematic timing out connections, ...).

Add-on "whyrejectme" will help your list_http_error.txt collection.


Information:

Our mission is clear - stay away from Cloudflare.

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

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

The owner of example.com can enable Cloudflare to whatever.example.com at any time without user's notice. It can be done from dash.cloudflare.com 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 example.com, we do not remove example.com from the database.

There is no exception.

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

  1. Open "Is MITM?" webpage.

  2. Input gitlab.com and mastodon.technology and click Skanu.

  3. Click testo for detailed scan.

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