Removing Your Site from the Wayback Machine

The easiest way to verify you own a domain is to put a text file in an easily accessible location and email info@archive.org asking for removal and link to it. This is where you’ll type your email and the text file for your website proof. The email needs to contain the request for everything along with links to the text file, you Keybase account, and whatever you want removed.
