I've reported these on YouTube yet they're still being recommended to me hours later. Clearly they're incapable of moderating their own platform. What's it going to take for them to start taking this seriously?
If both were implemented I suspect these sorts of scams would no longer be worth the effort.
They don't. You have to verify your channel first using a phone number.
But that brings obvious follow up question - should then such a big platform exist? IMO, even with all those problems - yes. Being able to easily share content with people around the world is and remove barriers for acquiring knowledge is a huge advancement. But I can totally see people disagree with that.
