Hotmail and Outlook

Microsoft randomly blacklists IP addresses for no reason whatsoever, making it impossible to send email to hotmail.com and outlook.com from those IP addresses. Each time this happens one has to contact Microsoft in order to get de-listed.
I got so fed up with the whole thing that I blacklisted Hotmail and Outlook; If I can't send email to Hotmail or Outlook, Hotmail and Outlook can't send mail to me.
