Many AI projects in academia or research get all of their web data from Common Crawl -- in addition to many not-AI usages of our dataset.

The folks who crawl more appear to mostly be folks who are doing grounding or RAG, and also AI companies who think that they can build a better foundational model by going big. We recommend that all of these folks respect robots.txt and rate limits.

Thank you!

But how can they aspire to do any of that if they cannot build a basic bot?

My case, which I know is the same for many people:

My content is updated infrequently. Common Crawl must have all of it. I do not block Common Crawl, and I see it (the genuine one from the published ranges; not the fakes) visiting frequently. Yet the LLM bots hit the same URLs all the time, multiple times a day.

I plan to start blocking more of them, even the User and Search variants. The situation is becoming absurd.

  • Well, yes, it is a bit distressing that ill behaved crawlers are causing a lot of damage -- and collateral damage, too, when well-behaved bots get blocked.
