I explained it before. I follow every one of my followers but some people take advantage of that by following than unfollowing me. This means that they're trying to make it seem like I followed them. Of course, since I follow everyone back, the numbers should be even on my account. When it shows I am following more people than my followers, it means someone unfollowed me. In order to find out who unfollowed me, I have to unfollow all my followers just to unfollow those people. It's actually pretty irritating for me too. It's frustrating, tiring and overall, a waste of my own time.
