Abstract: A method is disclosed which includes: receiving, from a third-party content provider, a link to a structured document on an external server, where the link is associated with a post of the online social network by the third-party content provider, and retrieving the structured document from the external server, where the structured document includes content and input fields.. This step is followed by extracting a predefined set of information from the structured document about the content and input fields of the structured document. The extracted set of information from the structured document are then evaluated to determine one or more feature-values of the structured document. A machine learning model is used to classify the structured document as an external lead-generation type page based on the one or more feature-values of the structured document and a notification is sent to the third-party content provider if the structured document is classified as an external lead-generation type page.

Abstract: An online system acts as a centralized, trusted intermediary in managing subscription products that a user of the online system has subscribed to. For example, a user may subscribe to receive a product from a variety of different third party systems. The user of the online system provides payment information and authorization information to the online system which stores them in association with a user profile belonging to the user of the online system. When a payment is required for a subscription product, the online system retrieves the payment information and verifies that the online system is authorized to provide a payment. Once verified, the online system provides a payment on behalf of the user to the third party system in exchange for provision of the subscription product to the user.
