Wikipedia is mostly going in the direction of just having very strict rules enforced via human review. If you get caught using LLMs and refuse to stop, you get banned. https://en.wikipedia.org/wiki/Wikipedia:Writing_articles_wit...

I think its working so far.

Wikipedia has always been different from other sites for leaning more on human labour instead of automated systems (so-called "soft security" https://meatballwiki.org/wiki/SoftSecurity ).
