Essays became way to easy to write with AI.
It used to be a basic filter that if text was long the author put a lot of thought (even if misguided) and effort (even if low quality) into it.

We need proof of work on long texts, a service that guarantees that the author was whipped for more than 20 lashes for this text to exists and thus we know he cared enough to publish it.
