All payments disabled due hacking attack.
All active accounts marked as suspicious.
Hacker used hacked email accounts for password reset request.
Please review your accounts and recheck your payment address.
I recommend change all your passwords and please use clean (not compromised) system for all your operations.
Use payment address locking if you use standalone bitcoin client.
If your payment address locked, but locked address not your or you do not able login, report about this immediately (through support form).
UPDATE:
Payments enabled for reviewed accounts and accounts with old locked payment address.
If you do not use payment address lock you have 2 options:
1) start use payment lock (only previously used addresses allowed), and request account activation by email (support form on site)
2) request account verification process by emai (support form on site).
