Commercial knowledge-graph and data-broker crawler; blocking prevents content resale.
Your call — blocking is a legitimate choice
Diffbot is Diffbot's training/data crawler. Blocking it opts your content out of Diffbot's model training and datasets. For this crawler, training and citation are separate decisions — citations are governed by the operator's retrieval crawler.
Common reasons to block: copyright or licensing policy, competitive sensitivity, paywalled content.
Common reasons to allow: maximum AI reach, research visibility, and being part of the datasets future models learn from.
