The disclosure includes a system and method for processing content spoilers. The system includes a controller, a progress module, a determination module, a warning module and a presentation module. The controller receives activity data describing an activity performed by a first user and content data published by a second user. The progress module determines a first progress stage for a subject associated with the activity based at least in part on the activity data. The determination module determines whether the content data includes a spoiler for the first user based at least in part on the first progress stage. Responsive to the determination that the content data includes the spoiler, the warning module obscures the content data published by the second user from the first user and generates a spoiler warning. The presentation module provides the spoiler warning to the first user.
