This is unfortunately not possible, because when the pool is closed then there is a responsibility occurs to pool members. And if pool members paid a fee to join to pool, then there should be a refund from the pool owner. We have to think from every different angle. Pool owner can sell his miners and quit anyway, then fee is paid to system not to pool owner.
Appreciate the clarification. That does make some sense regarding pool entry fees paid.
Could it be possible to sell ownership of a pool? Of course, your still end up potential for individuals to take over ownership and change fee structure of pool, which woul still be unfair to miners...of course, current owners could also do this.
Is there anything to stop pool owners from charging an entry fee and then a week later changing the fee structure to a very high fee, thus making the entry fee unfair or do owners choose between an entry fee or a fixed block fee.
For instance, could I charge people .05BTC to join a 0% fee pool and then suddenly change the fee structure to 100% after getting a bunch of users. Then withdraw and put the fee back to 0%, repeat...just thinking of ways the current setup might be abused.
