Problem with flagging copied videos.

Few of my videos has been copied, all of them is boosted with almost 100k views, probably mobile views, and a lot of likes, comments etc.
Videos promotes fake files, for PPD.

Problem is that I can't flag any of that videos with almost 50 flags, dislikes and etc. Before few weeks it was much easier.
Anyone know any effective way to get them down?

If your videos do not violate youtube ToS, then file a copyright complaint.
If they do violate it, then I am sorry, you are playing dirty and so does your competition. Nothing you can do about it besides flagging.

But there is karma waiting behind a corner for sure.
