Sys

Sys (abbreviation for System) is an automated Club Penguin account 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.

Trivia

 * When Club Penguin is running slowly, a glitch may occur which allows you to reply to postcards sent by puffles and at events. The message under the reply will read "Send this postcard to sys for 10 coins?".
 * Sys's mailbox is always full.
 * Sys overrides two account requirements: it ignores the usual minimum of 4 characters in a player name, and begins with a lowercase letter (like rsnail's account does).
 * Sys hasn't been seen on Club Penguin yet, and probably never will.
 * It is unknown if sys actually is a penguin, as it is probably a bot.
