Thanks a lot @thisjourney. I do find statistics fascinating. They provide a lot of insight. The strategy is very simple. These people follow a lot of users blindly in hope that some will follow them back. Some people do follow them back and after a while they simply unfollow all the people whom they had earlier followed. Now when you look at their profile..You will see a lot of people following them but only a few whom they are following. To a new user visiting their profile it would seem that the user is very popular on the platform..
