This is when someone follows a lot of people in the list and then unfollows them shortly thereafter. It's obviously something that our users don't like as they lose credits and don't get a new follower. When people churn the list they are effectively taking credits from others without giving anything in return. Twiends works on a system of mutual introduction. It's a trust system that says, I'll give you credits if you follow me for a reasonable amount of time and check me out.

People that just churn the list are not even giving their new friends a chance. Our systems monitor for aggressive follower churning and when certain thresholds are hit you may not find any new friends to follow. We also allow members to set drop filters on their settings page to filter out those that unfollow a lot.
