You had very low health after the fight with Joker in Grove Street. Then you entered a car while cracked and drove away from Grove Street by the thin alley, as far as the other player's won't see you. Then your health went from low to maximum. After that you drove back. While you did that, I was in spectate mode on you. I was the only administrator online, so nobody else could have set your health. You left the server, but when you came back I instantly banned you.
Which means you hacked. From here a RCON administrator decides what your punishment is and if you will be unbanned or stay banned.
