When the reputation changes you can see what specific post caused the change, the exception to this rule (are there others?) is when a user is removed.
When I see that my reputation has changed due to the removal of a user I would like to see a list of posts which the user has voted on and how the reputation has changed for each.
Why do I want this? Probably because I'm slightly obsessive, I'm not sure this feature actually has any real value. I would totally understand rejecting the request but I just thought I'd let my wishes known...
