Rahul has noticed that no matter what he posts, this one Twitter user whom he does not even know always replies with something inappropriate. What can Rahul do to prevent this from happening?

Rahul can block the user to stop them from interacting with his account and replying to his posts. Unfollowing only affects posts Rahul sees, and unfriending does not apply here because Twitter uses followers rather than friends. Rahul also cannot require Twitter to cancel someone’s profile.
