That's your opinion. Who do you think loses out in a situation like that? The ad network is getting paid regardless, the adtech company (DSP, etc) will pretend nothing is wrong unless their client has hard proof and the client (probably a company you buy things every day from) was simply trying to promote a new product and will assume performance was just off. Ultimately it is their customer that pays for all this by continuing to buy their products and use ad-powered platforms.
