While it's possible to load previous interfaces, special emoticons would only be visible client-side. Therefore, this person may have been using this Cloud Penguin add-in, which allows people to use emoticons from previous parties and have them show server-side as well. Although whatever the case, there doesn't seem to have been any harm done.
