 The Whirled Passport is a collection of stamps, which the player earns in connection to achievements in the Whirled, such as masking a thief, referring others to join, or uploading content.These stamps are similar to Trophies, which is another reward system in Whirled, except for the fact that stamps award the player coins for earning them.Because this feature promotes adding lots of friends, and uploading content to the store, many players have suggested that this might lead to issues with people spamming other players with friend requests, and a cluttered shop.
