It could be that this is only rumors/bad news that was created by several communities that are in contradiction with cryptocurrency I guess. because I see up to now, the content creators about crypto have no problems there is even a crypto influencer who does live streaming on youtube between Developer, expert analysis to discussing the development of cryptocurrency and Bitcoin price.
Nah if there's a blatant report of videos that sharing some phishing links or scam projects then most users will report it to them. It is the right of YouTube to handle those scammers sharing their scam links. One thing that I don't know yet is if YouTube might have deleted some legitimate crypto videos or vloggers videos. Then I think YouTube decided to remove any crypto related on their platform then.
Perhaps YouTube does not separate crypto scammers from the creators of legal crypto content. Its easier to remove everything than doing research and cleaning (although its a shame for such a large platform)
