Activision, the publisher of the Call of Duty franchise, has filed a Digital Millennium Copyright Act subpoena against Reddit,Inc. to "identify alleged infringers" who leaked information about an upcoming Call of Duty title on its site.

"Reddit is the service provider to which the subject of the subpoena-Reddit user 'Assyrian2410' – posted infringing Activision content," the filing, submitted Feb. 14 in California's Northern District Court, reads. "The Content infringes Activision's exclusive rights under copyright law. Specifically, it infringes Activision's rights in its popular video game Call of Duty: Modern Warfare."

The filing includes a link to the offending post, made in the Modern Warfare subreddit, which had a title of "I found this image online, not sure what it is," that has since been taken down.
