Preface: I don't believe this is a case of identity theft. Also, "name" here refers to first and last name. I Googled my name a couple days ago and found a YouTube profile with my name. As far as I know, that's the only thing my profile has in common with this profile. I PMed the other person, asking him to change his name on his profile. I realize that it's indeed possible that he has the same name, but my name is very unique. I also updated my channel's description to say "I am not xxxx." I could also: 1) Make a picture of myself my profile picture. 2) Ask YouTube to see if the guy is impersonating me. 3) Ask the guy to put his face either on his profile or in a video.
