LLMs broke ad fraud detection. Here's what that means.

Short summary

LLMs have made sophisticated ad fraud economically unstoppable by reducing bot generation costs to pennies—breaking the traditional detection arms race where offense and defense had symmetrical costs. 22% of global digital ad spend is wasted to fraud, projected to hit $172B by 2028. The solution isn't better detection algorithms but structural change: verified-engagement advertising where brands pay only for proof that real, identity-verified humans read and understood their content.
