Title says it all. for those that did not know. in 1.9 and above Player collosion is a thing. and if you are afk. someone can just remove that simply by pushing you. which in my eyes defeats the whole point of the AFK thing.
So I am suggesting that players cant push other players if they are AFK. I have seen plugins remove the collision completely. I dont see why it should be impossible for the AKF plugin to only do that while afk.
