What is CenturyBot?
Centurybot is a web crawler that identifies itself via a custom user agent as an indexing bot associated with the RightDAO website. According to publicly available information published at the URL referenced in its user agent, Centurybot is intended to crawl and index web pages at a conservative rate, retrieving pages infrequently to minimize impact on server resources. The crawler states that it respects standard web crawling conventions, including honoring robots.txt directives, and presents itself as a general-purpose indexing robot rather than a user-facing service or interactive system.
Despite these claims, Centurybot traffic is often difficult to independently verify, as it typically lacks consistent or trustworthy reverse DNS hostnames that would clearly associate requests with a known organization or infrastructure. There is also limited third-party documentation or widespread recognition of Centurybot compared to established search engine or analytics crawlers. Because of this, website operators encountering Centurybot should treat it as an unverified crawler and evaluate its behavior—such as crawl frequency, accessed URLs, and compliance with robots.txt—before deciding whether to allow or restrict its access.
