removing links is fine because a single DMCA takedown notice comprises of two parts: the first asserts that the person making the claim is the copyright owner, and the second is an affirmation that the person who is hosting the file does not have a license for the content.
so for eg. if there are 100 uploads of the same file but only a single takedown notice, the notice only confirms that that one user does not have a right to license that material. there would need to be 100 takedown notices (real and confirmed) to actually delete the file.
