Ah, all my vids got claimed as well, tried to email masangsoft, they didnt do anything about it, I dont really think they care for private servers unless that fake MAIET claims their content. I got one of my videos back by counter claiming with a fake law firm (illegal btw), you can try that, but the second time I tried it, youtube guessed that it was bullshit and manually refused
That taught me one thing though, youtube copyright laws are such unfair bullcrap.
