ClueWeb-Crawler is a bot in the academic research crawlers category, operated by Carnegie Mellon University.
ClueWeb-Crawler collects pages for the ClueWeb research corpora built by Carnegie Mellon University's Language Technologies Institute.
Research crawlers collect pages for university and non-profit studies of the web. Most are low volume and respect robots.txt. Block them there if you prefer not to take part.
ClueWeb-Crawler identifies itself with this user agent string:
ClueWeb-Crawler/1.0 (+https://boston.lti.cs.cmu.edu/CMU-ClueWeb-Crawler/; mailto:[email protected])Anyone can copy a user agent string. Transfon Security also checks where each request comes from, so a request that claims to be a known crawler but comes from the wrong network is treated as a fake, not as the real crawler.
We have not confirmed whether ClueWeb-Crawler follows robots.txt. Add a rule, then check your logs to see that it stopped. robots.txt is a plain text file at the root of your domain, such as https://example.com/robots.txt.

Allow ClueWeb-Crawler if it is a service you use, and keep its visits out of page views and ad requests either way.
Transfon Security for publishersClueWeb-Crawler is not a person. Exclude it from campaign and conversion data so reports reflect real visitors.
Transfon Security for advertisersAllow ClueWeb-Crawler only if it works for your store, and keep it away from cart and checkout.
Transfon Security for e-commerceIf ClueWeb-Crawler is a service you use, allow it on the endpoints it needs and block it elsewhere.
Transfon Security for SaaS and APIsrobots.txt is a request, not an enforcement. Transfon Security shows ClueWeb-Crawler by name in the Top Bots report, so you can see how often it visits and which pages it reads. Block or allow it with a User Agent rule, or slow it down with a rate limit decision rule.

ClueWeb-Crawler is a bot in the academic research crawlers category, operated by Carnegie Mellon University. ClueWeb-Crawler collects pages for the ClueWeb research corpora built by Carnegie Mellon University's Language Technologies Institute.
We have not confirmed whether ClueWeb-Crawler follows robots.txt. Add a robots.txt rule, then check your logs to see that it stopped, and block it by user agent if it did not.
Add "User-agent: ClueWeb-Crawler" followed by "Disallow: /" to the robots.txt file at the root of your site. To enforce it, block requests whose user agent contains "ClueWeb-Crawler" at your WAF. In Transfon Security that is one User Agent block rule.
No. robots.txt is voluntary, so ClueWeb-Crawler may not follow it, and anyone can send ClueWeb-Crawler's user agent, so a fake ClueWeb-Crawler ignores your rule. Enforce the rule where requests arrive, at your WAF, and check the source network.
