Received an e-mail to the Gmail that is linked to my hosting e-mail that I had a new user which was my name + 1 after I made a comment using Intense Debate. Thought nothing of it since it was my name and intense debate. Then started getting tons of my once daily digest e-mails that go to subscribers in my g-mail. A day later, a bunch of my subscribers said they got like twenty e-mails from old posts. Have changed all the passwords and deleted that user but what else should I do?
