I see accounts of people who quit the game 2 years ago. Scopely should start to sweep these accounts and this is how:
1- after 15 days send mail to owner of account. Everyone has put mails because of connection with facebook. In this mail there will be a warning that the account will be discontinued after a certain amount of time.
2- 30 day account inactivity = account in quarantine. The account is still on the server, but is not counted as server load anymore, thus the server load moves from full towards empty.
3- 15 days before permanent delete of account another mail.
4- after 3 months inactivity, account is permanently deleted. Recovery is only available if the server is not full. Those who want the account back, could put a notification system if another account was permantly deleted, so they can enter again.
I think this is the only solution to solve the inactivity problems on servers who are currently too big to merge. Im sure there’s a policy that prevents accounts to be deleted because of the investment, but with the warning system, it means people were aware and notified and therefor it was their decision to let the account be deleted.
With the recovery system, however, there’s always a way to come back (eventually). If scopely wants the game to survive another year, or even a few years, this is the solution.
