YoudaoBot

YoudaoBot is the search index crawler run by NetEase Youdao: Youdao. Its operator publishes no IP ranges or DNS names for it, so a request carrying this name cannot be verified. Treat the name in a log line as a claim.

Add a group that names it: "User-agent: YoudaoBot" followed by "Disallow: /". A crawler follows only the most specific group that names it, so once a group names YoudaoBot, rules under "User-agent: *" no longer apply to it; repeat in that group any Disallow lines you still want.

What blocking it changes

No. It indexes for a regional search engine; allowing it matters only if you serve that market.
