It seems there were 4 serial downvotes, and 3 got reversed.
Is the serial voting correction script supposed to revert all votes or just a few ones?
Per the FAQ, under "How does the system detect voting fraud":
When the system detects this pattern, all of the votes cast from that user to the user affected are reversed, and a "voting corrected" event is added to the affected user's reputation history to indicate what has occurred.
Assuming this is true, all the votes were reversed (another "supposed to be" next to the asterisk here). The moderators also might be able to check it using their diamondy powers, so use a chat ping or a custom flag to ask them about it.
