We hear this all the time, and it's been wrong going on eight years now. What's happened is that YOUR ACCOUNT has been compromised, due to no fault of ours, and it's now up to you to fix it.
FIRST things first... change both your MOJO password and your EMAIL password. If someone has access to either, they can access your Mojo account (the email allows them to get a "password reminder").
SECOND - The above will fix 9 out of 10 issues. However, if you find your account is still compromised, it's possible that your Internet connection itself is compromised. For instance, if you're using an "Open" wifi hotspot, there is no security whatsoever in what you send and receive. Your Mojo, email and much, much more can all be compromised quickly.
THIRD - If that's not the case, it's possible that the computer you're using has "key logging" or "spyware" installed on it. This type of software records everything that someone does or types while on their computer and can then be read at a later date by the perpetrator. To clear up this sort of problem, I'd recommend a software program called SUPER ANTISPYWARE. You can Google it up and run it yourself.
