For copyright violation claims, please follow the instructions outlined in the Copyright Policy page of TPT.
You'll want to be sure to include all of the required pieces of information listed. You can either use the form, or submit your own written notice to their Copyright Department by emailing [email protected]
If your notice contains all of the appropriate information, then TPT will promptly remove or disable access to the infringing material. Also note that the same page includes information on what to do if any of your products are removed due to alleged copyright infringement.
