Temporary reduce payout interval to 10min, reduce default minimal payout to 0.01 for new addresses, and restart pool.. but may be too late for this poloniex bacchanalia. Who can predict that?
I really don't see why wouldn't you be able to reduce minimal payout for OLD ADDRESSES. New addresses are on 0.01 old on 0.1 payout. Don't tell us that you can't it's more that you don't want cause I realy don't belive you don't know how.
I think he cant because its a scam...
