While reading an answer on a canonical question I found out that a domain of our formerly active contributor, MDMarra, has expired and registered by someone else. He has been referencing his blog here and there, leaving behind some links to the domain. Currently the links to
www.mdmarra.com are either showing some advertisements or redirecting to sites replicating news portals, potentially for phishing purposes.
Is there a way to automatically remove these links from the whole site? What should we do with such cases?
