never stolen from, however, ive let people borrow games enough times to learn my lesson about letting other people use my stuff. had a friend once who borrowed a Pokemon game from me. when he returned it the master ball was used, all the post game events i was waiting to play were finished, and several of my main team pokemon had their movesets changed. he wasnt even trying to be a jerk when he did it, he was fully conscious of all his actions.
