Random Copyright Striked

For a few days now I recieve Random Copyright Striked on videos that are 10+ years old. They were fine before and suddenly they are not.
The videos are not related either to each other, as no videos from the same series are not impacted (one is pokemon, one resident evil, one castlevania etc...)

I am pretty sure this is a troll that strikes videos at random just to piss people off and try to doxx them.
I've been on the website for more than 15 years and it is the first time it happens and the support doesn't respond.
