The DMCA does not create any obligations to take down anything. It provides that IF a service provider CHOOSES to take down material in response to a notice, it gains liability protection for any copyright infringement it was committing by hosting that material. If WordPress believes the notice is being used for censorship reasons, and there was no infringement occurring, and thus no actual risk of being liable for hosting it, then ignoring the notice is both perfectly legal and there's zero benefit to complying with the request.
