JustUnfollow is one of these popular apps that aim to let everybody have a smoother time around while they are on the Twitterverse. Specifically, it tackles one of the most recurrent mistakes there: the mass following of people who have nothing to do with you, and whose manual removal would take too long to be implemented.
JustUnfollow will take care of that, letting you apply a sort of filter and eradicate these followers that are not even following you back.
As it currently stands, this tool provides non-followers arranged in lists of 50 twitterers per page.
While mass following is certainly a mistake only newcomers make, it is also true that it is easy to end up amassing quite a few followers that don’t reciprocate, even when you are a long-time Twitterer. Active users who are always looking for fresh contacts are bound to face that predicament – expanding one’s circle and making new contacts is the idea of networking, after all. As a result, a tool like this one will appeal to Twitter users old and new alike.
