Can you add a report option for scripting?

Sorry for putting this in the wrong forum.

Everytime I play league and I am playing a champion with a skill shot I like to hide in a bush and shoot people randomly. Sometimes shoot at a target who isn't even main priority just to see what happens and I see alot of scripters on here.

Its so clear when someone is scripting because their champion will physically stop moving and turn them selves directly face first into a wall which would require someone to place their mouse in an uncomfortable position and then continue walking the direction they've chosen to go to, like them dodging was some kind of spastic twitch or a nervous tick of some kind.

I've seen many videos clearly showing how to identify a scripter on league, why isn't there a report option for it already? If a rioter got into like 5 ARAM matches they would be able to ban adleast four people for scripting, They're all over that game mode.

I've even played against someone using scripts on a ranked match, I made a fuss about it to my team and they said they didn't even care only because we were winning.

Is a report option for scripting impossible? or is there like something special I have to do to show proof that someone was scripting??
