Does VelenPublicWebCrawler respect robots.txt?

Yes. The operator documents that VelenPublicWebCrawler reads robots.txt and follows Disallow rules for its own token. Rules take effect on the next fetch of the file, which can be hours or days after you publish them.

How do I block VelenPublicWebCrawler?

Add the VelenPublicWebCrawler token to robots.txt with Disallow: /. If the crawler ignores robots.txt, match the user agent at your CDN or reverse proxy and return 403 there instead.

Q: How do I verify a request really came from VelenPublicWebCrawler?

You cannot, at least not from the request itself. No IP range file and no reverse-DNS convention have been published for this agent. The user-agent string is the only signal, and any client can send it, so treat a match as a claim rather than proof. Compare the source IP against hosting and datacenter ranges instead, and rate limit anything that behaves like a crawler.

VelenPublicWebCrawler is a bot operated by Velen Crawler that crawls pages into a dataset that is then reused or sold. "Our goal with this crawler is to build business datasets and machine learning models to better understand the web.". It is documented as honouring robots.txt, but no IP range list or reverse-DNS convention is published, so a request carrying this user agent cannot be proven genuine.

Verification

Is that really VelenPublicWebCrawler?

A user-agent header is a string the client chooses. Scrapers copy VelenPublicWebCrawler precisely because site owners allow it. No IP range file and no reverse-DNS convention have been published for this agent. The user-agent string is the only signal, and any client can send it, so treat a match as a claim rather than proof.

Paste the IP address from your access log below. You will see whether it belongs to a hosting provider, a residential proxy pool or a Tor exit, plus the ASN that announces it, which is what tells you whether the claim holds up.
