About the RoleCall crawler
If you run an opera company's website and noticed a visitor identifying itself as:
OperaAuditionMonitor/1.0 (+https://rolecall.cc/crawler)What it is
RoleCall is a free service that helps opera singers keep track of audition postings. Our crawler visits company websites that a human has manually reviewed and approved for monitoring — we never crawl a site nobody asked us to watch.
What it does
- Reads your
robots.txtfirst and follows it, including any crawl-delay. - Looks for pages about auditions, young artist programs, and casting calls — typically just a handful of pages per visit, not your whole site.
- Checks each of those pages roughly once a day at first, dropping to about once a week if nothing changes, so most visits are a single lightweight request.
- Re-scans the whole site about once a month in case a new page appears.
What it doesn't do
It doesn't submit forms, create accounts, follow links off your domain, or run anything but a plain page fetch (and, for a small number of JavaScript-heavy pages, a headless browser render — never any interaction beyond loading the page). It respects a minimum delay between requests even if your robots.txt allows faster.
Want it to stop?
Add this to your robots.txt and we'll stop within a day:
User-agent: OperaAuditionMonitor
Disallow: /Or email crawler@rolecall.cc and we'll remove your site from the catalog by hand.
