Its nearly impossible to completely secure the account, I havent been apart of the rs world for about a year so i'm not 100% on the exact procedure but you have to wipe everything, youre gonna need to delete the email (sure youcould find a guide on that somewhere around the interwebs), the questions, youre gonna need some previous passwords, the isp used to register, the estimate register date. Everything needed to recover, its basically impossible to completely secure the account. youre gonna have to do all of above and just hope that you can trust the guy.
