The problem is amplified by the game devs making it too easy to cheat
Previously all the skiddies seem to like CS:GO, cos CS:GO pays attention to the mouse cursor, so no-recoil cheats are trivial to write (A simple AHK MouseMove command will do it, no need for WinAPI calls to fake RawInput)
Now the flavor of the month seems to be Fortnite. Initially, this too was trivial to cheat in. It supports mouse and console controller, but when you fired with a controller, you got an aim assist.
So of course what they did was rig it up so that when they pressed fire on the mouse, it pressed a console controller trigger instead, so you got mouse aiming plus aim assist.
We have real problems on the AutoHotkey forum with douchebags consistently rocking up, no interest in learning to code, they just want hax handed to them on a plate, and they will download and run ANYTHING that they find that purports to be a cheat.
Then game devs get lazy, and make it so their game won't run if AHK is installed, screwing over legitimate users.
