My account profile says I joined 3 hours ago at the time of this post. I haven't created this account myself because my name cmkrc3vtvm86 is so random. I play swogh and have created one ea forums acoount before using the same email this account uses but It cannot be this because I created that multiple years ago. I have also used the swogh online shop which requires email to log in.

 Any idea how did this happen?
