The bottom line is you violated server rules by piloting a vehicle while not in a pilot slot, not being in TeamSpeak as a pilot and you took advantage of a bug or loophole in Arma mechanics that allowed you to bypass our server scripts that prevent non pilots from operating air vehicles.
I initially was going to lower the ban, but the more I read your initial appeal, the more it made me believe that the ban is appropriate.
To clear up the issue over “Some vehicles that allow players to switch from pilot to non-pilot seats can be piloted without a Vortex Pilot slot.” We have chosen to enforce this with server rules rather than scripts, as using scripts to prevent switching to pilot from non-pilot seats would be a large negative impact on performance.
I am going to talk to the admin that issued the ban. If you took control of another air vehicle after the initial kick for Rule #11, then I am going to leave the ban as permanent. If the admin, entered the ban for “Exploiting is a form of Hacking” after additional investigation into the kick, I will recommend that you be given another chance after a 7 day ban.
“I was initially kicked for #11 when I was never ever in a pilot slot. I did pilot a vehicle, but I wasn’t officially in a vortex pilot slot (the only slots that exclaim that you must be in TS3).” The rules clearly state (as mentioned by G0lden) “All pilots, UAV operator, and ATC must be on the NAK SQUAD TeamSpeak server (excluding NAK Elite). No pilot may be AFK.” If you were flying a vehicle you were a pilot, no matter what seat or role you were in. Your response after the kick just shows that you would rather try to find loopholes in the rules instead of trying to follow them.
" If it is your intention for non-vortex roles to be denied access from pilot seats, you must either specify this clearly in your rules or modify your seat permissions to stop people from doing it."
There is a script that prevents people from getting into the pilot seat from a non vortex slot, and the script did stop you numerous times. You then circumvented the script, by getting into the vehicle in another position and taking control. The rules do clearly state “This page does not cover all the rules; only the basic ones. If an Admin finds an unfitting behavior he will moderate it accordingly. We NAK Squad reserve the right to refuse access/service to anyone, at anytime, for any reason.”
“Many, many other players on your server have piloted vehicles without having the vortex role. I’ve seen none of them banned, kicked or even warned, yet as my luck would have it I was kicked for it.”
It seems your primary defence is you have seen other people do it, therefore it must be okay. But when you were kicked from the server for not being in TeamSpeak, instead of correcting the issue, you decided to try an challenge community guidelines. The rest of this point was coved very well by G0lden.
