This user changed his/her password recently.
I don't claim to know much about the workings of the forum but I've seen that this generally means an old account was hacked and is now getting sold or as user Quickseller said, the user just wants quick cash from what remains of his resources
Its stated in the subject that he can sign a message from an old address he posted on the forum.
My guess is that it's a bought account, with private keys to staked address also bought. Anyone else think that?
