Overview
Hatena is a search crawler used for search indexing, URL discovery, page rendering, result freshness, and search-quality checks.
Its primary user-agent pattern is Hatena; related patterns include Hatena::RUssia::Crawler/0.01; a representative HTTP user-agent is HatenaBlog-bot/0.02 Hatena::RUssia::Crawler/0.01 Hatena-Favicon/2 Hatena::Scissors/0.01 Hatena Antenna/2 HatenaBookmark/4.0 HatenaBookmark/0.03 Hatena::Fetcher/0.01 Hatena Star UserAgent/2.
Hatena 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.
Hatena is marked as respecting robots.txt directives for crawler access control.
Hatena can usually be allowed after confirming the source and monitoring request volume.
