AI is often blamed for eroding accountability inside marketing teams, but a more accurate read of what is happening is that AI is simply revealing organizations that never had real accountability to begin with. As automated systems take on more decisions without a person actively watching, the gaps in who is actually responsible stop being theoretical and start showing up in public, sometimes in embarrassing and legally risky ways.
A holiday campaign that got away from everyone
Consider a case involving a bookstore's holiday ad campaign, which launched with garbled text and swapped out product photos. The creative had already been approved before Meta's advertising AI altered it after the fact, without flagging the change to anyone on the marketing team. The photographer whose original work had been quietly replaced only learned about the problem after customers started publicly mocking the ads as AI slop. Nobody inside the company had been watching what happened to the campaign after it received sign off, because no one had been assigned to.
Big teams hide the gap, small teams cannot
The shape of the problem changes with the size of the organization, but the underlying issue is the same. At large companies, responsibility gets spread thin across multiple approval stages and departments, which can make it genuinely hard to point to one person who owns a given decision. At small teams, the opposite dynamic causes the same failure, a single employee often handles strategy, execution, and quality control at once, leaving no spare capacity to notice when an AI tool quietly changes something after it was already approved.
Approval is falling between the cracks
Guy Hanson, a vice president at Validity, put the problem plainly, saying approval increasingly falls between the cracks as AI takes on more of the building work. Teams are happy to take credit when an AI assisted campaign performs well, he noted, but when something goes wrong the failure tends to get reframed as a vendor issue or a tooling glitch rather than something the team itself is responsible for.
A three stage process with a blind spot in the middle
Campaigns now generally move through three stages, strategy, building, and approval. Strategy has largely stayed a human function, and approval, at least on paper, still belongs to a person. Building is where AI has taken over the most ground, and as that middle stage grows in scope and speed, it increasingly swallows the clear boundary that used to separate what a human decided from what a machine executed, leaving a structural blind spot exactly where accountability is supposed to live.
