We’re dropping Google Ads
If google would simply charge a "review fee" for new adverts, or when a target for an advert changes (via detection), that could cover the cost of manual review.  Another fee to "challenge" review, etc...This would allow good advertisers to pay once or twice a month for reviews on new ad campaigns and the spammy throw it all at the wall campaigns less likely.  But google isn't interested in quality... but quantity, so they can charge higher rates per view/click.
