My Email Is Being Used to Create Fake Profiles

I have been having some problems for the past year. A person with the email *** Email address is removed for privacy *** has been using my hotmail address to register on all sorts of websites using her own email address as a secondary email. I want to know how I can stop this person from doing that because it is VERY annoying and VERY frustrating having all these emails in my inbox that aren't mine. Can anyone help me out? (and yes I have used my email to erase such profiles she creates but they keep popping back up).
