You have to talk to the police about this guy so there will be a record of this stalking, and ruining your life stuff. I'm more concerned about your safety at this point. OK, about your channel I believe you should follow Michael's advice. If you fight this he has to prove to be the copyright owner. He will have to lawyer up and they'll remove the strike and put your video back up. This supposedly happened to a lady on some website forum I used to go to, minus the stalking part. She said she got the strike removed and the put her video back up when the guy didn't or couldn't go to lawyer up and provide proof. I completely understand why you are ticked off.
