It depends if your revenue scales as fast as abuse scales. Amazon should be able to keep on top of fraud easily, twice the sales means twice the revenue means they can afford twice the fraud checks, if they want to. That fake $30 "2tb microsd card" puts $30 of real money in their bank account. But for something like Twitter, revenue is only vaguely related to number of tweets. That "elon musk wants to give you free dogecoin" tweet doesn't make them a cent.
