Instant removal of props on kick

So yesterday a minge were spamming explosive barrels, it lagged really badly even before they exploded. He ignited one and i kicked him, but the barrels stayd and exploded.
It's a miraclle the server diden't crash. So i suggest on kick/ban the players props should be removed at once,
i dont know if this is hard to code. And it's not a big change, but it could be usefull.
