ImcONTrolIGYoU123

Once I was playing Roblox and got a friend request by the user of "MrJeffTheKing_Real" It was very normal! I accepted and we had a lot of fun. But all of that changed, I joined him in his own game called "Meeting!" But he was acting weird he said to me "Im c0NTrollG YOu" I checked his profile but his user was now "ImcONTrolIGYoU123" I unfriended him but I couldn't. I looked at his friends, just him having one but his friends user was "ImInYoUrHoUsE" That's weird so I went upstairs and seeing a man looking at me...
