To be honest, I see quite a lot of inappropriate content on YouTube's tending section pretty often. This can't have a net zero effect on youth.
Define inappropriate. The worst thing I've seen is somebody who swears or makes a fair amount of edgy jokes. I'm guessing you're outside the US since YouTube controls the trending tab pretty closely there.
