For webmasters
CallboardBot reads call pages for artists. Here is what it does and how to stop it.
Callboard lists open calls, grants, residencies, prizes and commissions for visual artists, curators and art writers. The crawler reads the listing page you publish and the call pages it links to, so each call can be shown with a link back to you.
What it reads
- One listing page per organiser, daily or weekly, and the call pages linked from it.
- Each live call page again every few days, so a changed deadline or a closed call is caught.
- Public pages only. It never signs in, fills a form or follows a link inside an application.
- At most one request every two seconds to any host, and at most 6 MB from a page.
- Only the call details. Artists apply on your own site, through a link from Callboard.
How it identifies itself
Every request carries this user agent string.
CallboardBot/1.0 (+https://callboard.art/bot)
How to allow or block it
It reads robots.txt before every page and obeys it. To keep it off your site, add this and it stops within six hours.
User-agent: CallboardBot Disallow: /
If a firewall or bot filter refuses it with a 403, an allow rule for the user agent above, or a feed of your calls, is enough for your calls to appear. Write to the organiser desk and we will set it up, or take your site off the list the same day.
