afk autokick not 100%

we've noticed a couple of times that if we are just standing around in a base without moving we sometimes get kicked for being afk. but then at other times a player is afk for multiple maps and does not get kicked. anyone know how to change that?

easy, move around just a little every 1-2 mins
There are tricks to make your mouse cursor move around a little bit, but I'd rather not say because I am pretty sure it is against the rules.

I think the issue it that since the player is dead, they are not supposed to move in the first place. is it possible to make it based on # of waves and motion in said waves? if they are shooting, they are not really afk but it might say they are.
