# /participants was Disallowed here on 2026-06-18 to shed crawler load off the legacy EC2
# box. That box is off, and the Disallow became actively harmful: it blocks CRAWLING, not
# INDEXING, so ~100k SEO-spam profiles stayed in Google's index and Googlebot could never
# see that they now 404. Re-allowed 2026-08-18 alongside the quarantine gate so those pages
# get recrawled and dropped. Crawl-delay stays.
