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

6 −2 pts

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

No OWNERDOMAIN declared

info

Ad systems without a public sellers.json

The ad system doesn't publish a readable sellers.json, so nobody can verify these lines. That's the ad system's gap, not the app's, so no points are deducted.

How to fixAsk the partner to publish sellers.json; until then buyers can't verify that path.
