Seeking help to find information about a particular yt channel whose impersonating me

So long story short some guy had impersonated me 2 years back and stole my identity to post meme videos related with my school teachers on Youtube. And lets just say that turned out pretty bad and destroyed my reputation.

I thought about leaving it the way it was,just reported it for impersonation and didnt feel to look back at it ever since then. But for some reason I revisited the channel and all I could see was YouTube still hasnt removed or blocked the channel LOL.

So all i am seeking is any help that you guys could give me, like any detail that isnt revealing too much or smth like that. Say for an example his previous username before changing it into mine.Any details through dm would be really helpful since this has been a real headache for me since the creation of this account.

Or just connecting me with somebody that could help me out is also fine with me. Just hit me up on dm or smth

Thanks in Advance.

And heres the youtube channel.
