More interestingly, if I host a lot of files on a file-deduped storage system, where there is only a single copy to any given file with many different directory entries pointing to it, if user A has a movie he hold rights to and user B hosts the same file (ending up on the same physical file connected to a different directory entry) without having the right to do it and user A sends me a takedown notice, will I really be forced to remove the file A had because I have to actually remove the file, not only the means of accessing it?
