Nudging allows IPSND members to adjust the SerialBot score for a submission with a photo attached by determining of the photo clearly shows the existence of the serial number submitted. However, nudging is only 'Open' until there is a clear determiniation of accuracy by members. If a serial number has more than 5 nudges and the total of those nudges is greater than 4 or less than -3, then the nudge will be closed automatically after the last nudge. If a submission is controversial and there are nudges in both the positive and negative direction, then the nudge will remain open until the balance of voting swings the point value beyond 3 (positive or negative).
