I uploaded a viral video (a recording of mobiks in Russia) on my personal facebook page some time ago.
Now a facebook page that reposts viral videos from the web (and has 70M followers) claimed ownership of my upload, in a clear copyright fraud. Facebook put a link to the "owner" under my upload.
Facebook proposes me to appeal to the fraudster only (which I did and it was rejected, of course). I didn't find a way to report a copyfraud.
How can you deal with that?
It isn't something that important to me, it's just a matter of principle.
Contacting support/appealing is unlikely to do much since their metric is tickets closed, whereas the legal metric is "number of things prevented from blowing up"
That said, there's a chance legal won't care, but it's the best option I think.
