There are probably a BILLION posts about this now and Riot still does nothing.
You probably all know about the people who have a script to just hold w to not get afk kicked. They just ruin the game with a very SIMPLE fix.

JUST CHECK IF THE PERSON HAS BOUGHT A GUN, DEALT DAMAGE, LEFT SPAWN, INTERACTED WITH ANYTHING.

I don't understand why Riot can't just implement this. If I am just dumb feel free to roast me in comments.
