Like fozzy said, this would be utmost Sea Burns fault for shooting the barrel. He needs better aim and should've killed Spy instead of shooting the barrel. But that's the proper way of doing things, you're not supposed to shoot the barrel but the player holding it. Because if you shoot the barrel, it'll cause damage to other players around, which may fall under whoever is holding it, but in truth it's actually the person who shot it.

So in conclusion, not bannable. rejected.
