Twitter has its own goods and bads. I was always wondering about an easy way to block unwanted Twitter followers. I have come across Nest Unclutterer, which is an amazing web application which allows you to filter out all the unwanted Twitter followers.
Usually you come across Twitter profiles who follow you expecting you to follow them. They are neither your friends, clients or acquaintances. Those are actually the profiles of the Twitter marketers.
Such people follow thousands of people ad thousands of people follow them too. And task to unfollow all such profiles is very time consuming task.
You can use Nest Unclutterer which access your profile data and you can ask it to filter out all those profiles who are following any number of people (as mentioned by you).
Then this Twitter application displays you with all such profiles. Then you can select them as per your choice in order to unfollow them. No doubt, this is one of the best ways to block unwanted Twitter followers.
