Findings

Each finding lists the exact lines involved. These are mechanical checks of public files, not fraud verdicts.

warning

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

20 −20 pts

The ad system's current sellers.json doesn't list these accounts, so buyers that validate the chain can't match them. Usually leftovers from closed accounts or old partners.

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

DIRECT lines pointing to intermediaries

4 −5 pts

The line says DIRECT, but the ad system lists that account as an INTERMEDIARY. Buyers doing supply path optimization may treat this as misrepresentation.

How to fixUse DIRECT only for accounts your company controls; change the rest to RESELLER.

DIRECT accounts registered to another domain

24 −8 pts

How to fixIf the account is yours under another domain, declare it with OWNERDOMAIN=<that domain>; otherwise mark it RESELLER.
