Ad Stacking Scam Prosecutions
Ad Stacking Scam: Concept Overview
Ad Stacking is a type of digital advertising fraud where multiple ads are stacked on top of each other in a single ad placement. Only the top ad is visible to the user, but advertisers are charged for all ads in the stack, inflating costs fraudulently.

Often automated using scripts, bots, or hidden ad placements.
Violates contracts, anti-fraud policies, and digital marketing laws.
