I've often wondered how much influence one really gains doing the follow/unfollow method. I mean, I suspect most of these types are just "social media coaches" following other "social media coaches". I suspect most accounts that have roughly the same number of followers and following above 500 are like this. I'd be interested in seeing a CTR for links published like this (though, not so interested that I'd do this scummy thing). Really if you're following over a thousand people, are you really paying attention to any?
