Roomate used my account to troll

Recently while i was off at work my roomate, who knows most of the passwords to my accounts, decided to log on and troll in online ranked. I have since gotten home and changed my password, and he will no longer be living with me. I understand that the punishment on my account is deserved do to the actions taken, however does this mean that i can never earn honor level 5 or end of season rewards? The reason why my roommate did this is because i convinced his girlfriend to leave him because he's an ass.
