There should be no doubt that the flat earth online topic explosion is a psyop. Obama mentioned either flat earth or flat earth society in at least three different speeches that I have seen and those are pretty much marching orders. The number one target was and is the truther community, knowing that such a target would include a rather large chunk of online Christianity, and that targeting was done by way of what is known as astro-turfing, (using trolls as you say), and we can all see around here how successful that targeting has been. The entire online truther community has been overrun by the flat earth meme, and was literally blindsided because it came in like a flood, seemingly out of nowhere. There is no doubt it was planned and executed on a rather large scale right from the start, (Clif High at HalfPastHuman, the bot watcher, said in one interview I heard, that his intelligence points to the DOD, ("E Ring", disinfo hub)). But see, now I have introduced my own little quasi-conspiracy theory just by what I have said. However it had to come from somewhere: a couple thousand people did not just all wake up one day, which happened to be right around the same day, and all decide to start posting flat earth videos on YouTube.
