‎Created claim: comment (P126): "Many Direct vendors sell a publisher's inventory not directly to a DSP, but to another exchange. Ads.txt files use 'Reseller' rows to indicate to buyers this is allowed. For instance, Ads4You may be a Direct partner but integrates with AppNexus to sell the traffic, in which case Ads4You would ask the pub to add a Reseller row that lists their ID tied to AppNexus (the "Reseller"). "
