the bowl, as bots see itThe bowl is empty. Last time, Googlebot stole the A Very Large JSON, 17 days ago.
Identification
Its full user-agent string, exactly as it arrives at the gate:
There is no operator to verify against. This name is what software calls itself when nobody gave it one.
No operator stands behind this name, so there is nothing to check its visits against.
How to block CrawlCheck
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 CrawlCheck's next visit. Nothing else on your site needs to change.
# Block CrawlCheck from the whole site User-agent: CrawlCheck 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: CrawlCheck Allow: / Disallow: /members/

Where it comes from
Scripts and scanners run from wherever their owners rent a server. These are the networks behind the visits on file:
No network data for these visits yet. The zoo looks networks up in a local database, which may still be downloading.
Networks and countries come from the visitor's IP address, looked up in a local copy of the DB-IP database. The addresses themselves are never stored.
