Of course he can change the payout scheme to something less risky for him. But while the pool is PPS and the wallet is empty, the pool is bankrupt because users are not/cannot be payed out according to the advertised payment scheme.
That IS an issue.
308BTC with ~100 owed is not bankrupt.
I'm curious as to where you're pulling this bizarre definition of bankruptcy from... If I'm a week late on a credit card payment, I'm bankrupt?
ed:
The wallet has 7, with 301.37834078 BTC immature... the wallet will grow by ~25.18 in about 5 more blocks.
ed2:
after looking more at the payout rules, I'm pretty sure it's due to the 'If the balance for an address is greater than 1.0 BTC, a payout is done.' rule... so, yes, it is probably making proportional payments to anyone over 1.0 btc... which essentially just screws everyone below 60000mhash
