It's a great paper, and a great application of machine learning! Though, the FBUs had worse readability than NBUs. I think you're misinterpreting the readability index - higher is worse, not better. From the paper: "Users who get banned in the future (FBUs) (a) write less similarly to other users in the same thread, (b) write posts that are harder to read (i.e., have a higher readability index), and (c) express less positive emotion."
