Before submitting your pull-request:

• name of the pull request should be "Add: domain, domain, domain (proxy + DNS)" or "Remove: domain (static), domain (DNS only), domain (static)"
• do not ask for removal of actually affected websites (any websites using cloudflare reverse proxy)

HOW TO REMOVE YOUR SITE

1. Verify the site is static and contains no user or sensitive data (I will remove it immediately once I confirm)

OR

1. Verify ownership, send me an email from @yourdomain.com, post a random nonce on the domain, or provide keybase proof
2. Verify you did not use the Cloudflare proxy service during the affected period
