Well Hotmail has just played the trick on me & I have a paid for account.
Says my account has been blocked:
Your account has been blocked
Why are you seeing this?
Someone may have used your account to send out a lot of junk messages (or something else that violates the Windows Live Terms of Service).
We're here to help you get your account back.
What do you need to do?
We'll walk you through a few steps to verify that you own the account, then have you change your password in case someone else has been accessing your account. It should only take a few minutes and then you'll be unblocked and on your way.
We've cleaned your account settings
Often customers get here because someone else has access to your account and are using it without your knowledge to send spam. To protect you and your contacts, we've removed any Hotmail auto-replies or linked accounts you may have had.
Then it says this:
Where should we send your verification code?
Here's the contact information we have for you.

I already have a code
So I ask it to send to my alternate address and.... I've yet to receive a code.
I've contacted them via Twit ter and through the Feedback form on their site.
The account was logged on btw - I didn't use it for about 15 minutes & when I returned to it it told me I'd been logged out because I'd been away for so long.
