I recently noticed a
-255 on my reputations on May 25 due the removal of a user. Apparently, the same reputation drop also happened to many other users who have been around for a while. So the user who left or was removed on May 25 must have been an active member of the community for quite some time and contributed at least by voting a lot (perhaps also by asking/answering many questions).
Just out of curiosity: who was this person? Does anyone know the reason for his/her departure?
