The Editors Protecting Wikipedia from AI Hoaxes

A group of Wikipedia editors have formed WikiProject AI Cleanup, 'a collaboration to combat the increasing problem of unsourced, poorly-written AI-generated content on Wikipedia.' From a report: The group's goal is to protect one of the world's largest repositories of information from the same kind of misleading AI-generated information that has plagued Google search results, books sold on Amazon, and academic journals. 'A few of us had noticed the prevalence of unnatural writing that showed clear signs of being AI-generated, and we managed to replicate similar 'styles' using ChatGPT,' Ilyas Lebleu, a founding member of WikiProject AI Cleanup, told me in an email. 'Discovering some common AI catchphrases allowed us to quickly spot some of the most egregious examples of generated articles, which we quickly wanted to formalize into an organized project to compile our findings and techniques.'

In many cases, WikiProject AI Cleanup finds AI-generated content on Wikipedia with the same methods others have used to find AI-generated content in scientific journals and Google Books, namely by searching for phrases commonly used by ChatGPT. One egregious example is this Wikipedia article about the Chester Mental Health Center, which in November of 2023 included the phrase 'As of my last knowledge update in January 2022,' referring to the last time the large language model was updated.
