The Daily Beast article isn't much help, talking about Pepe the Frog and "shitposting", with the banner picture, presumably the most egregious example they could publish, being Hillary's face with the caption "Too Big to Jail". Partisan, sure, but well within the realm of normal politics these days.
I know people expect more from their corporate leaders, but this shouldn't really be surprising to anyone given the context

Essentially taking comments you might find on /r/The_Donald and posting them on real life billboards.
I think I can get the idea. But could you provide an example from him?
I don't have any examples of Palmer shitposting, because his scheme never really got off the ground. A generic example of a shitpost would be if say, someone posted in this thread this image: http://i.imgur.com/QoZHVLs.jpg and demanded that we only post spiderman memes, instead of talking about the intended topic.
Some people call posting humorous nonsense on Facebook or Twitter as "shitposting" as well. Doesn't add anything, but can be amusing in small doses.
