This seems to be getting missed, but those kids apps are serving ads for adults. Google has gone way out of their way to make it confusing to block mobile ads (you used to have to add a blacklist domain.) Last year they removed support for that and required advertisers to check an option within the ad campaign. Earlier this year they removed that option. This is a win for advertisers, a loss for publishers and ad networks making money from mis-targeted ads.
