Honestly I think this highlights how divorced eng is from real world usage, otherwise he'd know this shit happens. every.damn.day.
ad tech is a house of cards and makes me reconsider working at Google every day.
I actually disagree, primarily because of the auction. It's an incredibly clever way to ensure Google's incentives are aligned with the advertisers'. Assuming rational bidders, Google can only charge more per click if the clicks deliver more value to the advertisers. If Google just sends a bunch of garbage clicks to the advertisers, they will just lower their bids.
