It's my understanding that the player previously known as Milograd has had his delete-on-sight designation overturned, and is once again playing NationStates under a new puppet. I'm not sure which puppet, but that isn't really relevant to this discussion. As far as I know, this is the first time a delete-on-sight designation has ever been revisited and overturned, excluding by appealing the rules violation that led to the delete-on-sight designation and Moderation finding in favor of the appeal. It's my understanding that was not the case in this situation.
EDIT: It appears I was misinformed, in a pretty epic way, and I'm really embarrassed, so a moderator can lock this if they'd like.
