Hello Turbo_Thunder,
I am that admin who banned you, I've noticed that you fell down to the water due a roleplay situation, but I just wondered because you were losing HP while you were in water, suddenly you became superman and escaped from that area. Usage of fly hack was obvious.
So yeah I didn't know why you're losing HP, but as you said you had "Shark CLEO" mod installed which is considered "illegal mod" and it's not allowed too.
It's up to HQ to decide about your unban. I suggest you to remove all of the illegal mods/hacks from your game directory if HQ decided to give you another chance!
Good luck!
