<b>The ads.txt line that gets your file truncated</b>
Confirmed: crawlers cap ads.txt fetches — oversized files past the practical read limit get partially parsed, and entries below the cut silently stop authorizing demand. Publishers who appended every SSP's boilerplate now have direct sellers buried under 4,000 lines of reseller cruft.
— Move your highest-yield direct lines to the top
— Strip duplicate RESELLER entries for SSPs you dropped
— Validate the file parses to the last line, not just the first 100
Impact: your best seat may not be authorizing at all. Confidence: confirmed.
