To piggyback on what @turbo07 said, remember not all of these are AFK'rs. If you look at their guns and they are centerlined, that means they never connected to battle and are probably having technical difficulties. Currently ISPs are having some issues keep up with the serious increase in traffic for them and many have switches and servers down because of this and are currently working on them.
We are in discussion with several companies about this and this is why I mention it. I know it is frustrating, but unfortunately if they are not going AFK, as in driving somewhere and parking (which I have seen recently, and if you see that please submit a ticket with the replay of them doing that, so we can fix that issue) they may not just being going AFK.
