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

add "example.net"
... to /split/cloudflare_e.txt

**But the website X no longer using Cloudflare!**
Are you sure? *Remove* it from /split/ list and *add* to "[ex_cloudflare_users.txt](cloudflare_users/ex_cloudflare_users.txt)".
- Above is how Siteground-hosted([INAP](https://www.inap.com/press-release/inap-completes-acquisition-singlehop/);[Singlehop](https://www.siteground.com/blog/siteground-partners-singlehop/)) sites often appear to Tor visitors when timeouts/tarpitting doesn't occur.

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, ...).
- 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_".
- 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?**
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
</summary>
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.
If `the owner` moved away from `cloudflare`**completely**, you are welcome to add `example.com` to the "[ex_cloudflare_users.txt](cloudflare_users/ex_cloudflare_users.txt)" - after checking `example.com` with online tool below.
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.`
