Who responds to the DMCA complaint if the content uploader is missing, for example if they have died? It looks trivial to wipe out everything via a DMCA complaint. All you have to do is wait until the uploader is unable to respond. Given enough time, this happens to all human uploaders. Nothing is safe. This part of our cultural history can be wiped from existence.
