everybody who is Dolphin or higher (e.g. has enough RCs to claim accounts) and does not use the RCs otherwise, should stack up on claimed_accounts to create accounts for free if needed.
Your account has enough power to claim an account per day. Why not setup a little cronjob somewhere to autoclaim every time you have enough RCs? I did it for my account with beempy and get a new a claimed_account token every 3-4 days.
