RedFortressAdsTxtBot is operated by Narrative Logic 2025, LLC, dba Red Fortress. It collects public advertising supply-chain transparency files for research and analysis.
What it fetches
RedFortressAdsTxtBot requests the standard transparency files that publishers and intermediaries publish specifically to be read by automated systems:
/ads.txtand/app-ads.txt, per the IAB Tech Lab ads.txt specification/sellers.json, per the IAB Tech Lab sellers.json specification
How it identifies itself
RedFortressAdsTxtBot sends the User-Agent string above on every request, so its traffic can be identified in your logs. Requests are made at a low rate and spread across many domains.
Why we do this
Transparency files exist so that buyers can verify who is authorized to sell advertising inventory. Reading them at scale is how those declarations get checked, and how discrepancies between them come to light.
