Twitter is still having a tough time rolling out its disappearing “fleets.” The social network confirmed to TechCrunch that it’s fixing a bug that let you see fleets after the 24-hour cutoff. If you used a set of leaked keys that allowed access to Twitter’s “firehose,” you could see and download expired fleets without letting the creator know you’d read them.
The bug effectively allowed anyone to access and download a user’s fleets without triggering a notification that the user’s fleet had been read and by whom. The implication is that this bug could be abused to archive a user’s fleets after they expire.
The solution ensures that fleets expire properly. A Twitter spokesperson said the fix should be “rolling out shortly.” The ephemeral posts will still reside on Twitter’s servers for up to 30 days, and it might preserve them for longer if they violate rules.
Fleets launched as a not-so-subtle rival to the Stories at rivals like Instagram and Snapchat, but it has had teething troubles over the past few days. In addition to lagging and crashes, users discovered that fleets didn’t respect block settings and opened the door to harassment. Twitter said it’s fixing these issues, but that could leave you waiting a while until fleets are truly polished.
