After spectating Gavlyn for an admittedly unnecessary amount of time I believe they are not hacking. I believe you all are misinterpreting a natural advantage in TTT. As a traitor, Gavlyn has the element of surprise knowing they can kill someone at any time and the other person most likely won't expect it. While a player is innocent they do not have the freedom to kill whoever they want, so when they are attacked they now enter a moment of panic to defend themselves and most likely their aim is becoming worse due to the panicked state.
Long story short Gavlyn has the element of surprise as a T but not as an innocent. *EDIT* It is worth noting they have 500+ hours in CSGO, while the skills do not entirely transfer between games, experience does. They obviously know how an FPS game works and likely are decent at them if they've spent that much time on one.
I have a recording to back my claim which I will upload at a later time if requested by staff.
