Except it doesn't revert the +2 reputation for accepting an answer.
When a question gets deleted, its answers are also considered "implicitly deleted." So why does the question's OP keep the +2 reputation?
My account shows this inconsistency. I
have (had) 103 reputation, and I gained the excess +2 reputation by accepting an answer to a question of mine (did that a long time ago) which is now deleted. Why wasn't the reputation negated?
