I don’t just think this will happen; I think it’s already happening. Harder to pull off here, but already extremely prevalent on Reddit and other popular social spaces. And part of the reason it works is that a significant subset of
human commenters write rather poorly and are not hard to beat, to say nothing of the evolving tools.
But don’t take my word for it. Go spend some time experimenting with the state of the art and run some of your own tests with it. Assuming you yourself are not one of these bots, what you find might surprise you.
