Overview
kb.dk_bot is a search crawler from Netarkivet used for search indexing, URL discovery, page rendering, result freshness, and search-quality checks.
Its primary user-agent pattern is netarkivindsamling; a representative HTTP user-agent is Mozilla/5.0 (compatible; heritrix/3.4.0 +https://www.kb.dk/netarkivindsamling/) Firefox/57.
kb.dk_bot 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.
kb.dk_bot is marked as not reliably governed by robots.txt directives; use server-side rules if the traffic should be restricted.
kb.dk_bot should be reviewed against site policy, source evidence, crawl rate, and requested paths before a permanent allow or block rule is created.
