Archived selling minecraft accounts and changing their pass later on !

hey guys
so this guy wanted some goodies off me and offered to give me his minecraft account.
he gave me user pass and everything and it worked so i traded him and took a picture of everything
i changed the password and it was working fine till now. he changed the password and blocked me on steam a while back..
