Remove inactive players from the ladder
When a ladder player or part of a team has been inactive for 6 full days, they are automatically removed from the ladder, as per the current "remove me from ladder" functionality. This would hopefully include seasonal ladders as well.
After 6 days, the player has been fully autobooted from every ladder game they were in at the time they stopped playing. Having them continue to get games only hurts them and the players that they played against previously. Future games are uneventful and take up game slots for their opponents. There are no positive effects of staying in the ladder while not playing games. If the player returns they can re-enter the ladder at any time with no penalty.
Inactive players are now automatically removed from the ladder! Thanks for the suggestion.
