LocalChalkBot reads public event listings and calendar feeds on venue websites so people can find what's happening near them. It follows robots.txt, reads only a few pages per site, and visits a site every few days when shows are coming up, and less often otherwise. It also re-reads the pages listings came from to check they still match, up to once a day for new listings.
To stop it, add this to your robots.txt: User-agent: LocalChalkBot and Disallow: /. To remove a listing or ask a question, email hello@getonthebill.com.
