I don't have a link, but I have seen exactly what he's talking about, which probably means that it is an established business model and multiple actors are doing it.

A similar thing I have randomly come across multiple times on YouTube are videos consisting of a still AI image of a white person mistreating a black person (e.g. a white police officer screaming with rage at a black man eating in a diner) and an AI voiceover text telling a GPT-generated story hashtagged #heartwarming, e.g. "The white police officer was violent against the black man... What he didn't know was this was a highly decorated veteran!"

Some of these are clearly getting picked up by the algorithm and drawing hundreds of thousands of views. The factories behind these are probably halfway around the world but realized the race relations of a large economy can be exploited for profit or geopolitics.
