Crawler policy

DuneCompetitorMonitor/1.0

This crawler reads public ad-transparency pages (Meta Ad Library, Google Ads Transparency Center) and the YouTube Data API on behalf of advertisers who track the brands they compete with. It never signs in, never carries a session, never works around a block, and identifies itself on every request.

How it behaves

At most one request per second to any host, and one visit per brand per day.
Reads only what the page shows a logged-out visitor. No accounts, no cookies, no fingerprint spoofing.
A 403, a redirect to a login page, or a rate limit is treated as a request to leave: the crawler pauses for hours and backs off further on repeat.
Creatives are kept as reduced previews with a link back to their public library entry — never a full-resolution copy, never a video file.
