• when the obtained third party user data is mapped to an existing user of the online host system, identifying an existing host system record associated with the existing user and updating the identified existing host system record in accordance with the obtained third party user data;
• when the obtained third party user data is not mapped to any existing user of the online host system, creating a new user profile for the user, creating a new host system record associated with the new user profile, and populating the new host system record with at least some of the obtained third party user data;
• and
