According to reverse engineer Jane Manchun Wong, editing a tweet with Twitter’s future edit button may leave a digital trail of your tweet’s history. Manchun Wong says in a tweet that the edit function appears to have a “immutable” quality, which means that when a tweet is modified, Twitter may create a whole new tweet while keeping prior versions of that tweet.
“It appears that Twitter’s method to Update Tweet is immutable,” Manchun Wong explains. “Instead of mutating the Tweet text within the same Tweet (same ID), it re-creates a new Tweet with the corrected content, along with a list of the old Tweets prior to that edit.”
