Facebook won't tell you when you've been unfriended - the functionality simply isn't built into user experience. After all, discovering that another human doesn't care about you (or can't stand you, dependent on your level of douchiness) isn't generally considered good news.
But this does little to sate the burning curiosity about who has deleted you, why they've deleted you, and what exactly they think you did wrong.
Clearly this is madness as most un-frienders have long-since dropped off your social radar, but the undiscovered well of human crazy runs deep, and social media is a bucket attached to an infinite stretch of rope.
Which brings us to the matter at hand: it's now possible to discover who has removed you as a friend. Masochists rejoice!
Who Deleted Me takes snapshots of your friends list over time. By comparing the before and after lists, it calculates who has dropped you like a stone-cold villain.
This means that Who Deleted Me won't be able to pick up unfriending activity dating before its first scan. So don't go in expecting a list of everyone who's ever removed you.
The service is available as an app for iPhone or Android, or if using a computer, an extension for Chrome or Firefox. Install at your own peril.
