Excluded-area leakage

Advertising semantics

A requested exclusion zone (e.g. exclude a competitor's trade area or a control market) can still receive delivery if the platform's exclusion granularity is coarser than the requested boundary, or exclusion isn't supported and is silently dropped.

Detection

Delivered impressions reported inside the geographic bounds of a declared exclusion zone.

Mitigation

Pre-subtract exclusions in cell space and submit only the net-positive target rather than rely on platform-side exclusion support
Reconcile delivery against the exclusion boundary every flight
