I had the same story once. But this wasn't a hacker actually, it was 1 of my friends in school. He asked me, if i can give him my login & password to play some tf2 I said ok and give'D a limit for him in time. When the time passed, he was still offline. I logged in (kicking him out) and told one of my another school friends to finish playing. But that bitch was still using my login, even when he recived the massage from my friend №2. That bitch was keeping using my account, so we started fighting for login (LOLOLOLOL, we were pressing the login button after each other). After 30 min... He was tired and gone back to his account, saying that he will come for mine one again. I changed my password and started resting. Next day... He started asking my password, again... I said: FUCK YOU, GO BACK TO YOUR LOGIN AND BUY THE GODDAMN TEAM FORTRESS 2. He: Pleaseeeeeeeeeeeeeeeeeeeee!!! I said the same that I said first time (almost). After 10 min, the conversation stopped. ===================================================== So meh, there are TOO much idiots in Internet.
