§ I.

Identification

Its full user-agent string, exactly as it arrives at the gate:

User-Agent
$ pi-crawler/1.0 (+https://github.com/pi-crawler; async crawler)

There is no operator to verify against. This name is what software calls itself when nobody gave it one.

Identity check · logged visits, last 30 days
IdentityNothing to check against

No operator stands behind this name, so there is nothing to check its visits against.

§ II.

How to block pi-crawler

Add these two lines to the robots.txt file at the root of your site. Well-behaved crawlers read it before they crawl, so the change applies from pi-crawler's next visit. Nothing else on your site needs to change.

robots.txt
# Block pi-crawler from the whole site
User-agent: pi-crawler
Disallow: /

Or let it visit but keep it away from part of the site:

# Let it in, but keep it out of one room
User-agent: pi-crawler
Allow: /
Disallow: /members/
