The listed use here is search. Someone asking an assistant to open a page is using it for an immediate answer. An owner may permit that request and block automatic training collection.

How many sites block it?

A User-agent line names it in 608 files, 9.9% of 6,171 readable files. Whole-site bans, written Disallow: /, total 427, or 6.9%. That leaves 5,744 without a recorded ban.

Across Tranco’s top 1,000 ranks, there were 552 readable files. Among them, 89 files carry the name, or 16.1%, with 58 files blocking the whole site. Blocking is more common among the leading sites, at 10.5%. Farther down, 369 of 5,619 files record a block, 6.6% of that group.

Counts include a whole-site ban in a User-agent: * group if no named group overrides it. Of 427 blocks, 182 come only from that general rule, without naming this crawler. The counted overlap is 245 files, with 363 files naming it without banning all paths. Missing names account for 5,563 files. Repeating a name or changing its capitalization does not increase the naming total.

Has that changed since August?

Between August and October, 25 sites that had blocked it stopped and 22 started, so 3 fewer of the same 5,889 sites block it. A further 376 blocked it in both months, and 5,466 did so in neither. Keeping the sites the same lets us count changes in their rules.

August’s full sample had 425 blocks among 6,236 readable files. October’s was 427 among 6,171. Those monthly totals also reflect which files we could read on each visit.
