Yes, but I had started a dedicated thread (can't find it now) for the question of possible key violations and it was confirmed from numerous sources that submitting multiple turns from same computer should not cause key violation. It makes sense for it allows one player to sub for a teammate in a team game, it allows to create setups in which a player may control more than one nation. I guess it also allows hot seat to work. Only issue is using same key from different computers (rights violation).

That is why I find the stales due to invalid key strange. It doesn't sit well with confirmed behavior as described above.
