Someone posted Youtube video telling that my friend username is a scammer. Actually he wasn't. The username is unique and it's his main username on almost all forums so it hurts his business so much! We have reported the video but it's still there for 2 days. How can we deindex or outrank the video to page 2 or 3 or just even out of top 10. It's now top 2 of his username SERP. Thank you!
