It is a possibility that your computer may have been compromised and evil doers were trying to get into here with your login to spam or get at the master member list. I suggest doing a full scan of your computer with the latest anti virus program that you have. There could be something lurking in the shadows of your computer trying to get all of your logins and PWs. I know it is a pain but you should change your PWs every so often to prevent your accounts from being hacked. This same suggestion should be for all members as well since there was a MacAfee report out recently that several servers around the world had been hacked for years unnoticed.
