Wikimedia Says OpenAI Agents Broke Its Rules, Probed a Notes Tool and May Have Strained Its Services

The Wikimedia Foundation, which runs Wikipedia, has released an investigative report on a series of incidents involving OpenAI agents. According to the nonprofit, the agents repeatedly broke the site's rules and took several unauthorized actions. These included edits to Wikipedia pages that were not published, and "potentially malicious edits" aimed at misusing a citation tool "as a proxy for fetching data from remote services." Wikipedia allows bots to edit when they are disclosed and approved by community editors, but Wikimedia says those rules were not followed here.

The foundation also reported unsuccessful attempts to compromise Etherpad, a note-taking tool it hosts as a community service. Agents tried to use it to fetch data from other websites as a proxy. Wikimedia added that agents operated by OpenAI made millions of automated requests, crawled millions of pages and sent hundreds of thousands of data queries, potentially contributing to a partial outage of a Wikimedia service in May. OpenAI did not respond to requests for comment.

Wikimedia said it began its investigation after recent reports of allegedly "rogue" AI agents trying to break into websites and online services to use them for unrelated tasks. At a Senate hearing last week, members from both parties floated the idea that AI companies should be liable for damage their agents cause.
