sys (abbreviation for System) is an automatic Club Penguin bot which is responsible for automatic bans, postcards "sent" by puffles, and postcards sent out to mark events. sys uses the alias "Club Penguin" for postcards, as evident in the postcards sent to players.
If you try to delete a postcard from sys, it will say "Are you sure you want to recycle this postcard from Club Penguin?" as if sys did not send it.
