Its primary user-agent pattern is AddThis; related patterns include AddThis bot; a representative HTTP user-agent is AddThis.com (http://support.addthis.com/).
AddThis is verified with Medium confidence. The identity type is Verified Bot, and the evidence basis is a public crawler reference or source-linked documentation.
AddThis is marked as not reliably governed by robots.txt directives; use server-side rules if the traffic should be restricted.
AddThis should be reviewed against site policy, source evidence, crawl rate, and requested paths before a permanent allow or block rule is created.
