Also, the revenue of large ad platforms are pretty correlated with efficacy, because of conversion tracking and competitive bidding. IE, advertisers pay $x per widget sale. If a widget sale requires twice as many clicks because of fake clicks, the market will react pretty efficiently halve the price of clicks. It's not perfect and adding noise/volatility bothers the industry, but it will be really hard to affect much at scale. ..maybe targeting one industry at a time, causing mayhem, and going after advertiser confidence in the platforms.
