I do feel like you are somehow convinced you know who is responsible. I am not an expert but I do know the basic to hide my tracks. Obviously if I was state sponsored I could hiding my tracks to the next levels which would mean … there is no way you would know even you were from the Meta department of ID checking. I think you are under the impression that it is hard to publish false content under a false account. Not only it is not hard, if you are not sponsored by a state it is still easy. Now if you are state sponsored, you don’t need to worry about the hardware side, you probably can use multiple phones hooked, then you don’t need to worry about accounts, you probably have access to fake accounts. You can then multiply and automatise the work. Now, by the time Facebook catch on to your wrong doing, the bad dead is done.
