> It can't be spun as 'we sell so many ads we can't check them all'. It's 'we don't check them all because that's cheaper'. Unless the price of the ad is so low that paying to review it is a loss, in which case don't sell at that price, or treat it as a loss leader. Or maybe more precisely: "we don't check them all because our business model wouldn't support it." The arrogant (and false) implication there is that making their business model work is the highest priority, and all of society's other priorities should take a back seat to it. If your business model only works with shitty automation that doesn't actually do its job, then you need to find a different business model.
