"Dec 28 7:11 AM We disabled payouts last night after reports of multiple user accounts being compromised. The issue and the users affected were identified and Multipool will be reimbursing any funds that were lost as a result of the attack. We'll be contacting affected users directly via email and also locking down some additional accounts that could have potentially been compromised. Payouts should be processing again shortly. Thanks for your patience."
That explains it...
Hi, this is to verify I logged in for the first time in many months using the same user ID that I use here & changed one payout address & made four payout requests (admittedly dust, but still...)
