Rules for every crawler, written User-agent: *, count here too. Of 722 blocks, 225 come only from that general rule, without naming this crawler. We found 497 files naming it and blocking the whole site, along with 90 files naming it without that ban. Another 5,584 files omit the name. We ignore capitalization and repeated names.

Has that changed since August?

Between August and October, 29 sites that had blocked it stopped and 75 started, so 46 more of the same 5,889 sites block it. A further 603 blocked it in both months, and 5,182 did so in neither. Keeping the sites the same lets us count changes in their rules.

August’s full sample had 658 blocks among 6,236 readable files. October’s was 722 among 6,171. Those monthly totals also reflect which files we could read on each visit.
