This is essentially machine-generated spam.

The irony of machine-generated slop to fight machine-generated slop would be funny, if it weren't for the implications. How long before people start sharing ai-spam lists, both pro-ai and anti-ai?

Just like with email, at some point these share-lists will be adopted by the big corporates, and just like with email will make life hard for the small players.

Once a website appears on one of these lists, legitimately or otherwise, what'll be the reputational damage hurting appearance in search indexes? There have already been examples of Google delisting or dropping websites in search results.

Will there be a process to appeal these blacklists? Based on how things work with email, I doubt this will be a meaningful process. It's essentially an arms race, with the little folks getting crushed by juggernauts on all sides.

This project's selective protection of the major players reinforces that effect; from the README:
