Website is NOT using Cloudflare (& blocking you)

List name Description
list_error403.txt Returns HTTP Error 403 (Forbidden)
list_error462.txt Returns HTTP Error 462
list_customerror.txt Returns custom error message (not HTTP 403)
list_other.txt any other form of tor-hostility or mistreatment
list_siteground.txt siteground.com is a Tor-hostile hosting service that indiscriminately DoSes all Tor users with the collective judgement: "our system thinks you might be a robot!" Sometimes the site functions, and sometimes it times out, but the robot accusation is very common.
list_formerly_tor-hostile.txt was previously on one of the above tor-hostile lists 

IMPORTANT: Please add only "Base Domain" or "(base domain)[space](comment here)"

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

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

    if "example.net" is blocking Tor
        add "example.net"

Some websites use other companies with the CloudFlare business model.

Add them to /not_cloudflare/ (formerly "TorBlocker Hall of Shame Part I")

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

This add-on will help your list_error403 collection.
