Block songs and artists ENTIRELY, not just from recommended music

I don’t want my kids to be able to search for and play certain songs or artists. They should not be able to ask google or whatever to play “poopy poopy fart fart” and have Deezer play it if I have it blocked. “explicit” filters don't work well enough. I should be able to control which songs should NEVER play, even if directly searched for and requested, not just what shows up in a shuffle or flow or whatever.
