The following links to various organizations who welcome third-party piracy reports or provide guidance on how to report piracy.

COPYRIGHT OWNERS ONLY: STOP ONLINE PIRACY OF YOUR WORK BY FILING A DMCA TAKEDOWN NOTICE
If you are a copyright owner whose work is being infringing online, you can send a DMCA takedown notice to the website where the infringement is taking place requesting that the infringing material, activity or link be taken down. Before sending a DMCA notice please understand that:
Only copyright owners and their agents are able to send a DMCA notice to have their work taken down (if you are not the copyright owner report the piracy to the copyright owner through the directory above and they can decide whether to submit a DMCA notice);
A DMCA takedown notice can be sent regardless of whether the work has been registered with the U.S. Copyright Office;
It may be good practice to first consider whether the use may qualify as a fair use before sending a notice.
Here are links to DMCA takedown submission forms for some of the most popular websites and content platforms:
