History
Same as shown above since 2026-09-28. We re-check it every few days.
We read each site's robots.txt as an ordinary visitor sees it and test the home page path (/) for each crawler, using the same rules Google documents (most specific group, longest matching rule). Some sites serve a different robots.txt to verified crawlers, and a site can allow the home page but block other sections, so treat this as what the public file says, not a guarantee.
