My last post on “Breaking Bing Cashback” seems to have gotten Microsoft’s attention.  Here’s a letter from their lawyer asking me to remove the post:

They also closed my account:

The purpose of my post was to show an implementation problem, not to encourage defrauding Microsoft.  I am surprised they would go through this much trouble to make me take down information that is obvious to anyone reading their documentation. I don’t like dealing with lawyers, so I’ve decided to comply with their request.  The post is gone.  I will still write a “non-technical” post on all the problems I see with Bing Cashback in the next few days.
