VelenPublicWebCrawler

VelenPublicWebCrawler is the training crawler run by Velen: collects public web pages for Velen's datasets. Its operator publishes no IP ranges or DNS names for it, so a request carrying this name cannot be verified. Treat the name in a log line as a claim.

Allow: /

Add a group that names it: "User-agent: VelenPublicWebCrawler" followed by "Disallow: /". A crawler follows only the most specific group that names it, so once a group names VelenPublicWebCrawler, rules under "User-agent: *" no longer apply to it; repeat in that group any Disallow lines you still want.

What blocking it changes

No. It collects pages for training. Refusing it is a policy choice about training, separate from whether answer engines can reach, read and quote the site.
