1. A computer-implemented method for confirming authorship of documents, performed on a server having at least one processor and memory storing at least one program for execution by the at least one processor to perform the method, comprising: conditionally confirming entity authorship of a first document hosted on a first website of a first domain, the first document including an authorship identifier associated with the domain and unique to the entity but not the first document, when: (i) a profile for the entity is associated with the authorship identifier, and (ii) the profile for the entity includes a confirmation status that 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 first document by the entity, permitting application of a confirmed authorship process to the first document; and responsive to failing to confirm authorship of the first document by the entity, barring application of the confirmed authorship process to the first document.
