The difficulty with this is that the fake Trump posts are generated by mashing together words and phrases that the real Trump uses. So they aren't fake at all, it is all Trump. Not surprising that people can't tell them apart. Almost 30 years ago I posted a Markov chain text generator to comp.sources.games. Can't locate the original, but found Rich Salz's cleaned-up version at http://mailing-list-archive.cryptoanarchy.wiki/archive/1995/11/89e2939b0d041c79d02b21ca6a5d5d593559f0371be2b6cd1f476b107bf5ad7e/ http://mailing-list-archive.cryptoanarchy.wiki/archive/1995/... You just put in text and you get text out that has the same statistics for three-word sequences. More modern approaches avoid the Memento effect of not remembering anything other than the previous two words, but it's the same idea: you take Trump text in and just rearrange it.
