On a lot of DarkRP servers, there is a nifty addon that allows prop to be translucent, and go through people. This allow people not to get prop pushed. How this work, whenever you pick up a prop, it becomes translucent, and can go through people. This will break people trying to prop push you, but they can still prop push other people props. Maybe you guys can find a way to make this go through other people props, but if there on your team it won't go through it.
