A mass unfollow feature on Instagram would help users clear their feed of unwanted content, reducing the clutter caused by catfish, spam, and bots. This can enhance the user experience by ensuring they only see posts from genuine accounts they care about. Additionally, it can improve the platform's overall integrity and security by discouraging malicious activities. Other benefits include better engagement with authentic followers, improved mental well-being by avoiding unwanted interactions, and a more personalized, enjoyable social media experience.
