Could you give me some searching clues to hunt down this or a similar profile?

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.

Several of the Reddit "AmITheAsshole"-style subs have a significant number of posts which are either AI or sloppy creative writing.

Mass-produced outrage bait isn't new, and it's available in a thousand flavors. But AI has accelerated this process, at least for people who don't notice when they're getting played (or who don't want to notice).

Looks like this

Here are a few examples of ones where right-wing influencers are making AI-shop videos of people complaining about losing SNAP benefits:

Note how that second one all uses the same script, "I have 7 babies from 7 different baby daddies!"
