With the advances in text generation by machines that looks, but isn't quite accurate (aka GPT-3), seems like it would be easily gamed (given access to GPT-3). Even without GPT-3, if the content being prioritized is mere text, I'm sure that for a pile of money, I could generate something that looks like Wikipedia, in the sense that it's a giant pile of mostly text, but it would make zero sense to a human reader. (Building an SEO farm to boost ranking of not-wikpedia is left as an exercise for the reader.)
