You cant bot without delays. Don't use delays in your code and you're fine.

- Send 10 keys to WoW at once, because of GCD WoW still only performs one action. Not botting.

- Send 1 key to WoW, delay, another key, delay, etc, WoW now performs multiple actions from your one keypress. Botting

An if-else will still only perform one action on the WoW client. Not botting.
