Closed to all crawlers
robots.txt disallows every crawler at the site root, so we read the policy and fetched no page. The access findings below stand; everything that would need the page itself was excluded rather than scored zero.

Crawler policy
Read from facebook.com/robots.txt. A crawler is listed as blocked when the rules deny it the site root. This operator names 6 AI crawlers explicitly, which means the policy is deliberate rather than inherited from a wildcard rule.
