There is a massive difference between using binds/alias (what you are describing as a "script") and using third party software such as autohotkey or razer synapse(or whatever bloatware that comes bundled with your $200 dollar 1337 gaming keyboard) to press your spacebar 4 times instead of 1 every time you press it in order to make it easier to bhop. Besides, i doubt he even knows about using mouswheel to bhop since he's holding w while hopping.
Stop. You're just making yourself look dumb
"Surround sound" is a buzzword to sell trash gaming headsets that have cheap and garbage components
Yes, but there is no way to enforce this so we'll just have to deal with it. Sucks, really.
Binding your mousewheel to +jump does not create 4 spaces when you type in chat. Its clear he's using some sort of third party software to press his spacebar multiple times on one input. The demo takes less than 5 minutes to watch btw, if you're curious on how it looks.
Since you're fine with using scripts, what is your opinion on autohotkey scripts that automatically compensate for recoil, or a script that automatically fires as soon as your recoil resets when tap-shooting.
