in 2 days ive played 3 matches with and against aimbot users in EU

first 2 matches was the same guy and the second time its someone with a different name.

uses aimbot that snaps to target whenever the person shoots.

I have reported them multiple times and didn't get word if anything happened to them. I just want to know if this aimbot problem is aware at riotgames and if its being worked on. it really sucks to play with or against them and it leaves me not wanting to play no more.
