Oh, now I know what you mean. It doesn't turn your head because it's client side. If you were looking at another player's standpoint, you are turning your head like a normal killAura. The client is actually using a thing called "silent" so you don't see it on your side.
Ah, that makes sense. I was testing Wolfram to see what hacks would be easily noticed. ClickAura will forever be KillAura
Spigot is already an amazing anticheat, but getting a better anticheat won't solve anything. If the anticheat gets better, that means the client's bypasses will get better. This is the reason why private clients like XIV are private, because their bypasses are secret. NoCheatPlus+ is good, BUT, it isn't perfect. Like private client, "XIV', uses bypasses that are secret, so NoCheatPlus+ creators won't be able to make a update to patch the bypass. This is why Public clients tend to be worse than Private Clients.
