I actually think they were trying to say something strange is going on, which I think is pretty obvious given their stats, and that they have no idea who's doing it or why, partially because Facebook can't be bothered to look into it or at least get back to them about it. That to me sounds like FB is aware of the issue and isn't interested in discussing it. That's the subtext imo. My own suspicion would be because someone is gaming their ads and they haven't been able to prevent it as of yet, and not because they themselves are gaming the numbers. No doubt they believe that discussing it is tacit admission that they haven't been able to prevent it, which is bad for business.
