DIRECT lines inconsistent with public data

131 −21 pts

The ads.txt specification defines DIRECT as an account the publisher directly controls. For these lines, either the ad system's own sellers.json lists the account as INTERMEDIARY, or the same account is marked DIRECT in the files of 3 or more unrelated companies. Either way, the public data does not support the DIRECT label. Buyers that use DIRECT labels in supply-path decisions may treat these lines differently.

How to fixUse DIRECT only for accounts your company controls. Confirm with each partner whether the account is yours; if it isn't, the specification calls for RESELLER.

Seller IDs not listed in the ad system's sellers.json

1,434 −16 pts

The ad system's current sellers.json doesn't list these accounts, so buyers that validate the chain can't match them. Common causes are closed accounts or former partners.

How to fixAsk each partner whether the account is still active and request their current lines; remove lines for closed accounts.
