Recently, I've noticed a bunch of new users who have a small number of questions. They have received a number of downvotes on their first couple of questions or so; since they start out with 1 rep, it never changes because of the downvotes.
However, once they get their first upvote, it gives them the full amount of reputation without regard for the previous negative reputation. Is this intentional so as not to scare away new users, or just a bug?
(One example may be found here.)
