Actually, stealing any internet account can be amazingly simple. For example, if you have a dead (deleted, not used etc.) e-mail account which is still related to some of your other accounts you might have forgotten. All one needs to do is claim that e-mail account. It would then be pretty easy to find hints about your other accounts (usernames, possible passwords etc.) which ARE active.
And thats pretty much the easiest way to do it... hackers are usually much smarter than that though.
Remember kids, anonymity=/=safety!
