Like some have mentioned, just b/c a video gets flagged by viewers doesn't mean the video should be immediately taken down. Unfortunately the Youtube algorithm is flawed but with so much content being produced every minute, I guess it's hard to come up with a perfect system. Youtube treat some of their own creators "guilty" until proven "innocent" while the appeal process drags on, which is totally unfair.
Anyways, I peeked at your channel and objectively speaking, you're probably getting a lot of haters b/c of your body/looks. Whatever the case may be, some people have chosen to not like you and that may be the reason why it was flagged.
