The wording on many of these ads is odd. In hindsight they are clearly written by a non-native english writer, but perhaps the Facebook audience is used to awkward writing by their peers?
Cyber space is a high leverage domain which rules out the possibility of a shortage in resources from the opponent. It is also a recent evolving space which makes it more difficult to assess the opponents capabilities, reach and sophistication.
By its nature this operation seems to be part of a bigger destabilisation strategy, maybe a stress test to validate different tactics.
I would be really worried once the ads become well written which would increase the complexity of the situation since quality measures can be manipulated.
In other words once they can fake "fake news", things might get really weird.
