YouTube strikes?

Does anyone know about YouTube strikes? I have a YouTube channel and I’m doing well with it but I keep getting strikes. I cover Philly and Chicago and anything that’s viral. I’m having an issues with posting some of the up and coming artists. Some of them are underage but there’s little to no information on them to find that out and anything I posted was the same exact content that they post on their page. I tried to appeal it and got denied. Not sure what to do. If anyone knows anything of has any advice I’d appreciate the help. Thank you!
