If you receive a DMCA notification of alleged infringement and you believe in good faith that the allegedly infringing works have been removed or blocked by mistake or misidentification, then you may send a counter notification to Comcast. Upon Comcast's receipt of a counter notification that satisfies the requirements of the DMCA, Comcast will provide a copy of the counter notification to the person who sent the original notification of claimed infringement and will follow the DMCA's procedures with respect to a received counter notification. All counter notifications must satisfy the requirements of Section 512(g)(3) of the U.S. Copyright Act.
