This is a weird one.  I created an alias like a year ago, though I rarely use it.  A month or two ago, I started getting strange e-mails to that alias as if I had signed up for something.  It looked like someone had created a new MS account with an e-mail similar to my alias, and had typed it in wrong.  But I've received like 10 things from different services (including SKYPE!) indicating to me that they are intending to type their e-mail this way.  Is this 10 typos?  Or is something else going on with Outlook.com?  Could they somehow be using my alias?

Help!
