Feature Request: List Group Destroyers

[Sormik]

It would be nice to see who likes to destroy the group.
One idea would be the following:

1. someone joins the group
2. key started
3. the player leaves and gets +1 on his counter for the season

An advantage of this would be to see who destroys keys. With this counter you could see when creating the group how likely it is that a player leaves the group.
