Follower statistic

A follower statistic would be great to see who is following me just to get ride ons without rewarding me at all. I have some very loyal followers who always give me ride ons, and I return them ride ons daily and make sure that I don’t miss anyone. Others never reward me. And when I deactivate them, they suddenly come back and give a ride on. This is annoying. I would greatly appreciate a means that helps me clean up my follower list. It’s no use to have hundreds of them when they only follow to grab ride ons for themselves.
