I've seen it used as a newer evolution of trolling on Reddit. A user hops in to a somewhat nuanced discussion and gives a very curt and rude contradiction, and then just uses an LLM to generate walls of argumentative text after you respond with "What are you talking about and why are you being such a dick?"

Very low effort the ensnare someone and waste their time for a bit, even though it is pretty quickly obvious what they are doing.
