All YouTube creators need to be sure their channels have selected the "Not suitable for kids" setting. US law has caused them to requuire this and you can be individually prosecuted for even an unintentional depiction of anything which might even be remotely considered as being possibly harmful to any child. At best on YouTube if they themselves see any content they are worried about, your channel can be deleted in it's entirety- at best the concerned vids will be removed and possibly your entire channel suspended until you comply. This has already happened to several creators whose channels did not seem to me to be unfriendly or harmful to children. This per their recent policy change from a couple months ago which all of us should have received notification of.
