Nope, the hacker did not get banned.  You were not able to tell us who hacked you, or why.  I was assuming that the person who sold you the account hacked it, but you said you know them in real life, so I just did not pursue it.  Try to practice safe account responsibilities.  Change your e-mail password(s) and your account password(s) if you feel someone else may know them.
