Setting aside the fact this was definitely not unprompted, social engineering might be the one thing AI is actually better at than a human. That is after all one of the biggest uses for bots for a while now by way of spam bots trying to social engineer people into various activities.
It’s to feed the algorithms and get more views. They get paid based on the number of views a video gets. The higher the algorithm promotes a video, the more views they get. Getting lots of comments on a video causes the algorithm to promote it more. It costs the spammers almost nothing to shit out a quick thirst trap video but they need to get enough views to recoup that cost which means there is a minimum number of views they need to break even. It’s not a huge number as far as these platforms go, but it’s also not nothing so anything they can do to encourage more views is mandatory for them.
