I received a DMCA notice for a website I run that allows users to view videos hosted on other video hosts such as PutLocker, VideoSlasher, etc. I was asked to remove the videos, asked to identify the source of the videos, provide the number of pages views, identify third parties, and provide a detailed account of payments. The videos are hosted on other websites so I can't provide page views or payments. I haven't responded to their email, but I have taken down my website. Now what?Where do I find a copyright defense attorney? Also I believe it is a subpoena?
