Given that they also sent a claim regarding a map feature on the .com site that wasn't provided by that site, I'm not sure if any of the claims they throw at ISPs (DMCA or not) are even legit. The main issue is that the "free" team can't counter-claim without losing anonymity, so as far as bogus DMCA claims go, they're quite powerless. That's why I went for the WIPO dispute, which is based on their trademark and IMHO has the most leg to stand on, instead of relying on the unwillingness of the counterparty (whatfreewords) to defend themselves.
