Google doesn't choose which ads you see. Google says "These are the attributes of someone who deserves to see an ad" and companies bid on that ad space. That means that if the adult diaper company is ABSOLUTELY CERTAIN that you want their diapers, you will see nothing but adult diaper ads. Supposedly Google has some internal processes to try and punish you if you buy ad spots that don't convert or cause bounces or something, but I find it hard to believe google would give up money from stupid businesses like that.
