That lewd stuff that played in an ad

If this is also allowed on Playio, can I include it? But then I suddenly thought, these kinds of lewd ads are shown, and youngsters play too... is this okay? Even when downloading an app, it doesn't ask for terms of use or if you're 18+ or anything... Will it eventually get regulated...? Or is it better to report it if I find it? I'm not sure, so I'm asking. Lupesis, please tell me.
