This is in no way bannable. I make no argument that it is okay to abuse it knowingly. But it is SO easy to do without realizing it that it's basically impossible to be 100% sure that you are banning only people who abused it on purpose vs people who simply wore the wrong armor and used the wrong grenade. Would you actually be so much a douchenozzle as to ban people who had no idea they were triggering this glitch?
