blackhull bot — operator information
====================================

User-Agent: bhbot/1.0 (+https://bot.blackhull.systems)
Operator:   blackhull <bot@blackhull.systems>

WHAT IT DOES
  Fetches specific pages to answer questions, and re-checks a small number of
  watched pages to notice when they change. It does not crawl: it requests known
  URLs, never traverses links to discover new ones, and never harvests content
  in bulk.

HOW IT BEHAVES
  - Reads and obeys robots.txt, including Crawl-delay.
  - At most one request per domain every 2 seconds.
  - Sends If-Modified-Since, so an unchanged page costs you a 304 and no body.
  - Executes no JavaScript, loads no images/CSS/fonts, sends no cookies and no
    Referer.
  - Low volume: single-digit requests per site per day is typical.

HOW TO BLOCK IT
  Add to your robots.txt:

      User-agent: bhbot
      Disallow: /

  That is picked up within the hour. To slow it rather than block it, a
  Crawl-delay for bhbot is honoured exactly as stated:

      User-agent: bhbot
      Crawl-delay: 30

ON DOCUMENTED APIs
  robots.txt is a crawler-exclusion protocol. Some sites publish an API for
  programmatic use and also disallow it in robots.txt — PyPI, for example,
  disallows its JSON API alongside the /simple/ endpoint that pip itself
  depends on. Where that is the case, this bot may call the documented API
  deliberately, for one specific resource, at the same rate limits as anything
  else.

  It applies that narrowly and never: to evade a block or rate limit; on
  account, admin, checkout or search paths; or simply because data is valuable.
  If you would rather it did not do this on your site, email the address below
  and it will stop.
