Can someone post tweets without confirming a twitter account?

Someone made a twitter account from my old email, and published tweets. I had my password at all times, how did they do this?

Circa late 2009.

Is this even possible?

Please take in account everything I've written, before replying.

Thank you!
Why didn't I get a confirmation email?
