I might have to remove my youtube channel because another user just re-uploaded every single video of me.. please report him for impersonation or I'll remove my channel my next week https://www.youtube.com/watch?v=ESb4QK8jySA
this seems like a user not a bot. they uploaded literally every single video and doubled the time to seem not copying. I've had to submit every link to them which takes a while.. I just want free content at good quality to my viewers, not to be impersonated by a loser living in his parents basement.
I cannot stress this enough - watermark your videos.
It won't stop piracy, but if someone does pirate, there's embedded proof it's yours. Plus, if someone who is a fan of yours comes across the watermarked video on someone else's channel, they can know it's not you, so they can notify you.
