Methods and systems are provided for allowing users to recommend advertisements displayed in a third-party application running on a user device while not granting the third-party application privileges to send such recommendations on behalf of the user. A social network application installed on the user device, and separate from the third-party application, acts as a proxy for advertisement recommendation requests (e.g., indications that a user wishes to recommend an advertisement displayed), and a user is required to confirm all such recommendation actions. In this manner, a third-party application (e.g., a “malicious third-party application) cannot send advertisement recommendation requests, and/or requests to undo such recommendations, on its own as if it were the user.
