Can you explain what do you mean by shills? As far as I can remember, Coin bureau also talks about some coins in some videos, including their potential etc. I think that can be considered as shill, but probably not paid shilling.
Like you already heard, he doesn't shill any project because he was offered money to do so even if the project is not worth the praise,
Not all youtubers shill for money, some do so because they find the project good enough and want their followers to benefit from it as well, however a good number are paid to shill though.
