Cease And Desist of the Day: Sorry stalkers: Facebook has moved to block Dan Loewenherz’s Breakup Notifier — a Facebook app which lets users receive a notification when friends change their relationship status — after sending Loewenherz the following message:

To ensure positive user experiences on Platform, we run routine automated screens that take user feedback, machine learning and various algorithms into account and remove spammy applications. For example, if an application is making an inordinate number of stream.publish calls and receiving a large number of user reports, it may be removed by our automated systems to protect the user experience and the Platform ecosystem.

Before being shut down, Breakup Notifier managed to rack up a staggering three-and-a-half million users since its launch less than a week ago.
