My Twitter account was hacked last week, unknown to me until I finally logged into my email and Tweetdeck. I had taken the week off for half term holidays and was unaware of the problem until 2 days ago. Since then I have changed my password twice and it is hopefully all better now, but I hate the thought of all that spam coming out of my account.
Resolution: I will not allow just any application to use my Twitter password, only the tried and trusted from now on.
My deepest apologies to anyone who was affected by this.
