Windows 7: Will pinging disable user in Facebook War commander

I have a friend who says while playing War Commander he thinks his opponent is PINGING him which causes a disconnect.while he is disconnected the opponent wipes out all of his troops.

So, first is this possible for an opponent in this Facebook app/game to disable an opponent? (whether or not ithe iniating commandt is a ping or some other comnmand)




Second if this type of hack IS possible(has anyone else heard of this?) is there a way to prevent it?

thanks
