Probably this is one strategy of the scammers so that it will look legit when someone is thinking of sending to them. They will look at blockchain and says "Oh looks legit there are already money being sent". But then it is all false alarm. And they will only realise that they have fallen to it and it's too late.
Actually the only way scammer can have some victims is to make the crime looks legit by doing a free deposits. This is even happening on lots selfdrop ICOs where users will checked the smart contract if people are sending eth but they dont know its also the same team doing it and just rolling over thr funds.Or report it to Youtube themselves, I'm familiar with that site but many noobs don't check if the address is already reported to scam-alert.
Thats probably why Apple sued Youtube, cause there is a chance they are collaborating with these scammers, but they should handle the legality of their users to avoid their platform used for this kind of scams.Here is the details: https://decrypt.co/36442/apple-co-founder-sues-google-youtube-over-fake-bitcoin-giveaways
