Yeah, I mean, this is exactly why I stopped uploading SS episodes and inserts altogether: it wasn't worth the risk of losing everything else I uploaded to copyright strikes and what have you. And like LittleJerry says, technically and legally, they have the right to strike your uploads, because you are uploading copyrighted material without their permission or consent . . . and IIRC, wasn't it you who emailed SW about this a while back and they told you they would terminate accounts and channels if they had to because of this?
I wouldn't even bother making a dispute - YouTube only listens if it's some big corporation.
This is true. Just a few months ago, I discovered someone else on YouTube had stolen one of my Steve D'Monster videos: that's
my original content. I filed a claim to have it taken down for copyright infringement, but YouTube rejected my claim.
The only success I ever had in disputes was disputing third-party claims on videos utilizing production music that was composed specifically for free use anyway - even though those weren't completed until the eleventh hour.
