Overview
WMF Citoid is a feed fetcher from Wikimedia Foundation used for RSS or Atom feed polling, syndication refresh, subscription delivery, and content update checks.
Its primary user-agent pattern is Citoid/WMF; related patterns include Citoid/WMF, Wikimedia Citoid; a representative HTTP user-agent is Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/110.0.0.0 Safari/537.36 Citoid/WMF (mailto:noc@wikimedia.org).
WMF Citoid is Unverified at the identity-evidence level. The listed identity remains useful for detection, but this record does not currently contain authoritative evidence sufficient to authenticate the identity claim.
Robots.txt behavior is not currently confirmed.
WMF Citoid should be reviewed against site policy, source evidence, crawl rate, and requested paths before a permanent allow or block rule is created.
