You should provide more proof regarding this claim, just linking the profile of the accused and saying that he is YouTube bounty scammer or whatever is not enough.
Yeap agree with you. I don't think its a proper way to make scam accusation against someone. OP i wanna suggest you that please try to provide genuine evidences (screenshots, transaction details, videos or reliable sources) before calling anyone scammer otherwise your scam accusation will be useless. Its quite hard to decide wheather this guy is a scammer or not. You have just mentioned that "this guy is claiming YouTube bounty and you think he is a scammer". I am seeing complete lack of evidence here and hope you will update your topic with proper evidence and description (if you have)
