A system, computer-readable storage medium storing at least one program, and a computer-implemented method for confirming authorship of documents is presented. A document hosted on a website of a domain is accessed, where the document includes an authorship identifier asserting authorship of the document by an entity. Authorship of the document by the entity is conditionally confirmed when a profile for the entity is associated with the authorship identifier and when the profile for the entity indicates that the entity has confirmed that the authorship identifier is included in documents authored by the entity that are hosted on the first website of the first domain. Responsive to confirming authorship of the document by the entity, application of a confirmed authorship process to the document is permitted. Responsive to failing to confirm authorship of the document by the entity, application of the confirmed authorship process to the document is barred.
