Advertisers don't bear the costs of fraud. Intermediaries don't bear the cost of fraud.

Fraud is priced in. It drives down the value of all ad inventory in the market.

The costs of fraud end up being borne by legit publishers (who have to compete with fraud for the same ad budgets) and with copyright holders (whose work gets copied onto bottom-feeding sites.)
