Twitter is working to expand the use of its “misinformation” labels on misleading tweets. The company has developed a new feature, not yet live, that would pop up a “misleading information” label when a user tries to “Like” a tweet that’s been labeled as misinformation.

The feature was discovered by reverse engineer Jane Manchun Wong in the Twitter app code. She confirms the addition doesn’t prevent a user from continuing to “Like” the tweet, however — it just slows you down.
