1. Go to the biography.
   
2. click the "Actions" button and then select the "Report/Block User" link. On a profile, it is listed as "Report/Block This Person."
   
3. Select Send a complaint.
   
4. Select This person is impersonating.
   
5. Follow the instructions displayed on screen to complete the complaint.
