Should there be a "Friend Alert"

What I mean is whenever a friend deletes you there should be like a pm or something telling you who deleted you. There are many times I dont no who deleted me.

if you voted no plz say why. thanks

2 Reasons why I voted no:

Instant Messenger has the feature to recieve you instant notifications if you have been added as friend, not sure about the deletion though.
If you are good friends, or know them very well they wont delete you without a reason, if you have been arguing/inactive, you know why they deleted you.

There already are Friend alerts via the d2jsp Instant Messenger. There are no plans to add any other form of alert for these.
