There is one question the ad-verification industry has never cleanly answered, and almost all of its friction traces back to it: when a third-party vendor flags something, is that flag a veto or a suggestion? Can it block the transaction, or can it only advise against it? The industry mostly leaves this ambiguous on purpose.

It sounds like a technicality. It is actually a question of authority and liability. A veto means the vendor stops money from moving. A suggestion means the vendor raises a hand and someone else decides. Those are entirely different amounts of power, and entirely different distributions of blame.

The real question is who pays for a mistake

Every verifier is sometimes wrong. False positives and false negatives are inevitable. The veto-or-suggestion choice decides who eats that error. If the flag is a veto and it is wrong, the vendor has blocked a legitimate transaction and owns the loss. If the flag is only a suggestion and it is wrong, the buyer who ignored or heeded it owns the loss, and the vendor keeps its hands clean.

Authority and liability are the same coin. Whoever gets to block the deal is whoever should pay when the block was wrong, which is exactly why no one wants the veto.

This is why the "independent" checker is often less powerful than it appears. Real power would mean the veto, and the veto means owning the mistakes. So vendors tend to prefer the suggestion: the influence without the liability. Until the industry decides whether verification is a gate or a hint, its authority will stay deliberately, profitably unresolved.
