Publishers copy-paste every partner's lines and assume more = safer. It's the opposite signal now.
— Crawlers and buyers flag ads.txt files with hundreds of unverified RESELLER lines as supply-chain noise
— Stale lines for SSPs you no longer run create unauthorized-reseller risk on YOUR domain
— Buyers cross-check ads.txt against sellers.json; mismatches drop you from curated marketplaces
Lean and accurate beats comprehensive.
Impact: quarterly-prune dead lines; every entry should map to live, paying demand. (sourced)
