Not an advertiser but they generally know % of views ("impressions") to clicks (called click through rate) and percentage of clicks that turn into sales (called conversion rate).

For that reason, I don't think they're trying to get rid of human users completely, just the "troublemakers".

I think they want to lead the "silent majority" users into a bot advertorial content hellscape where they control all the levers of power and everything is for sale.
