It's a long running joke on the sub after being constantly accused of being bots (and probably bots created by Russian hackers closely working with Trump.)
It's really, really not. Accusations of Russian influence on Trump's campaign are common to the point of almost being a meme. So /r/the_donald turned it into one. Not much different than the "steel beams" meme.
This coming from a person who filters out /r/the_donald so I don't have to see it.
