As described in my twitter traffic blueprint, you often need to unfollow people who didn’t follow you back. Most of us used Twitter Karma for the task of unfollowing lots of people at once. It still is a good service but got less reliable lately. Several users reported bugs and errors, so I went out to look for an alternative.

I found a very nice twapp called mutuality at http://www.huitter.com/mutuality. It gives you three possibilities:

1. Unfollow all people who do not follow you back
2. Unfollow all people
3. Follow all people who follow you

A nice bonus feature is the exclude list, which lets you define a set of people you don’t wanna unfollow.

I tested huitter mutuality twice and I’m very pleased with the results. Do you have any other bulk unfollow sites or tools you wanna share? Please post a comment.
