There's a better way.

In fact, any third party crapola that you
use to unfollow people is not a good idea. Why
play with your valuable twitter account?
Use this:
Who Unfollowed Me on Twitter? | Friend or Follow
Type in any twitter name, and it shows you who
is not following back. Then, one at a time, you
can unfollow them. But, yes, you need to be logged
into twitter. But I always that via the twitter site.

You need to unfollow people for a lot of reasons. Here's
2 quick ones. I unfollow to maintain an almost perfect
balance of followers to following. You need to maintain
a high ratio anyway. This shows people you are worth
a follow because you follow back. Unfollowing also
pays back the idiots who ride your coattails just for
a little while to get some of your juice. I hate
those bas!@##$rds.

If you don't maintain a high enough ratio for the fraction:
followers/following, then eventually you won't be able to
follow anyone. Twitter has this in place so some fool
cannot just start following boatloads of people. The first
major point is 2,000. You can only follow 2,000 unless
your ratio is high. I forgot the ratio. It used to be 90%
or so. Which meant you could not follow more than 2000
unless 1800 were following you.

I unfollow more as a payback. Like I said, I hate those
clowns with a passion.

As another example, I don't want people to see something like me
following 10,000 with 9,000 followers. Make me look like an
easy touch to get a follow back, then dump me.

Thanks, i was looking for some decent tool to unfollow people who don't follow back. I will use the tool mentioned to clean up my twitter account.
