Computer implemented systems and methods for cross-platform spoiler blocking are provided herein. An example method includes ascertaining by a data platform data potentially available to a user of a service having a media object; identifying by the data platform at least one object revealed by the media object, the at least one object being associated with an application; receiving by the data platform metadata associated with the at least one object, the metadata indicative of whether the at least one object should be hidden from the user; determining by the data platform, based on the metadata, the at least one object is a potential spoiler; and blocking by the data platform, the user from interacting with the media object through the service.
