I'll contact the owner and see what they say. I'd be interested in getting the users refunded and my rent arrears paid. FWIW, at the end of the month, my SP rental with them ends and will not be renewed.
UPDATE: I'm told that minnowpond will be making an announcement post soon. Their dev has been working to improve the stability of the service. I'm also told that they are working on refunds to users but this will take some time as they manually audit the voting logs.
I have also offered to return the last rental payment I received if it will hasten refunds to the users, but I have not yet received a response.
UPDATE: minnowpond has said they can cover the refunds. I leave my offer open.
