Twitter’s new tweets, known as fleets, are supposed to last for only 24 hours. Bug allows fleets to be viewed and downloaded by other users, but without notifying author’s author.

Twitter spokesperson:’we’re aware of a bug accessible through a technical workaround where some fleets media URLs may be accessible after 24 hours’.’we are working on a fix that should be rolled out shortly,’ Twitter spokesperson said.

Twitter’s API does n’t return URLs for fleets that are older than 24 hours. Once the fix is rolled out, even if someone has a URL for active fleet, it wo n’t work after the expiration point.

During that 30 day period, a fleet is available in a user’s Twitter data downloads as long as Twitter is retaining a copy. The’seen by’ action is typically only available when someone views a fleet via the Twitter app.

Twitter is a bit late to the disappearing content party. The fleet allows users to briefly share text, videos, images, or other tweets. You can reply to one by tapping on it, which sends a direct message to the fleet’s creator.
