Writers can keep a Substack domain indefinitely so long as their publication remains active.
If a publication is inactive for more than three months and its subdomain is requested by another publisher, our policy is to ask the publisher for permission to reassign the subdomain ([name].substack.com) to the requester.
We may reassign a subdomain at any time at our discretion if we believe that the use of the subdomain poses a security risk to our platform, employees, or users.
Please note that we may decide to reassign a subdomain without a holder’s explicit permission if we believe the holder is exploiting the subdomain with no intention to become an active platform participant or publisher.
In order to keep any subdomain, activity on your publication should be authentic. We reserve the right to use our discretion when evaluating whether content has been published for the sole purpose of domain squatting.
