Well, after watching you all have been investigating all of this that hard I will share my ''script of autosniping''.
I've always been open about using ProGUI and I've been open about this to people who've asked me and I haven't just said that I have an autosnipe script. As some of you may know, I have a gaming mouse that has a click multiplier. That way, with one click you can do 2,3 or 5. On top of that, I have a pretty high CPM. Then, I can also customize the mouse to change the position of the buttons, and my right click was the wheel. Each angle of rotation is one click. I'll let you imagine the rest. Those high clicks that you have seen are becouse of that wheel change. I invite you to test it if you can customize the buttons of your mouses.
Whether these are cheats is up to you, but in all competitive games there are these kinds of hardware manipulations. Mouse in the case of PC and Scuff controllers in the case of Play
