Does nba.com block AI crawlers?
Partly. As of October 19, 2026, nba.com's robots.txt blocks none of the 17 AI crawlers we check from the whole site, but keeps 16 out of parts of it and allows 1 everywhere. 10 of them are named in a group of their own; the others follow its rules for every crawler.
It has no llms.txt (HTTP 404). The homepage answered HTTP 403 to ContextFetchBot, so there was nothing to measure.
Each crawler, by its robots.txt rules
From https://www.nba.com/robots.txt (10,036 bytes, 13 user-agent groups), parsed per RFC 9309. Blocked: no path allowed. Partly blocked: some paths disallowed. The rule counts are those of the groups that apply.
