How to guide on how to list stolen content on takedown notices

Source information declaration - Most takedown notices require clarity and specifics on the ownership and the original (or source) location of the content listed within the takedown notice sent to have content removed that has been stolen and posted without permission.

Takedown case managers at DMCA.com are unable to assume infringing (stolen) content source information. In order to process a takedown notice on your behalf, takedown case workers must be provided source information by content owner, copyright owner or takedown notice author.

It's imperative that we have a complete infringing source list to be sure that all infringing content is removed. We are unable to add to this information after the takedown request has been processed and sent.
