Late game AFKs are just as much of a douche like those early AFK

I just dunno why people need to AFK in games without valid reasons. If it is an actual emergency, client crashed or internet problems then it is understandable. Why bother trolling people if you just wanna ruin people's game? If these people just wanna AFK without any reason or just wanna troll players, why not don't bother coming back playing in the future? Hate these troll players with a passion.
