AFK Timer

I have joined so many empty servers its crazy. They arnt really 'empty' but filled with afk players. I do this sometimes. Life happens. But generally this leaves with only 1-2 people that are playing while the rest are afk in a full server (15 max??)

If there was an AFK timer of 15-20 minutes I feel would eliminate this emptiness. Would allow servers to feel full and fresh IMO with more ready and available competition
