No, the fact that he is clearly ducking and denying any wrongdoing in the face of evidence means there is no point in talking to him. Even if he did reach out to me, I doubt he would be made to stop plagiarizing, I mean he asked to point out which videos, as if he doesn't know.....
He says he is slandered but slander is when there is false statements made about someone, his plagiarism is proven with evidence ergo not slander.
So the fact that he is claiming he is being slandered shows his lack of morals and his inability to realize he is in the wrong or admit to any wrongdoing.
Its like catching someone with their hand in the cookie jar and they still have the gall to deny it.
Plus from what I read in this thread by others, he is still plagiarizing content.
