Possible timer for open world AFK'ers?

[Renik]

macgyver'd something together to press their controller/keyboard and keep them "active" while they were away at school/work/whatever.

This, it sucked having to go to the store or just to make food and find the game kicked you, forcing you to the log in process for a 3rd time...

AFK players have nothing to do with random kicks, this is a problem on your side, bandwidth, cable, wifi, router, or your isp routing, you can't "guarantee" it's not on your side, that word only shows how little you know about it, i suggest you to find a real solution instead of trying to punish inocent players.
