I would like to confirm that I made the account LuckyYOU myself and sold it long time ago and once he made a thread and asked for a loan and I signed a messaged there, I'll dig it in and will post an update here.
Why would you sign a message and essentially put yourself on the hook for someones loan? Sure you may have sold the acct and should have given them a signed message upon sale of said acct but after that you shouldnt be signing any other message for them.
