Meta knowingly earns 10% of its _overall_ sales from scams. https://www.cnbc.com/2025/11/06/meta-reportedly-projected-10...
It's more than that. The 10% is the scam ads that "won" the ad auctions. It doesn't include the effect of scam ads bidding up the market and increasing the price of non-scam ad wins. (Could also argue that the scam ad that won the slot for 10 cents would have gone for 9 cents without the scam and Meta's marginal revenue was only 1 cent... but if every ad is 1 cent more...) Same problem when you want to buy a home in…
They're probably taking that into account in their 10% of profit coming from ads estimate.
