You make compilation video right, some video stuff maybe registered to viral distributor such as Junkin, Rumble, ViralHog and ect. If you not pay for any video in your project maybe they are not needed to send you notification for 3rd party copyright, they can strike your channel anytime they want cuz they are have the copyright holder.
