Teracus- There is no way to tell the difference between a 'snipe' and a manually placed bid without asking the bidder. One can place a bid at the last second without the aid of AS.
Nabors- Teracus is right in one aspect. The other bidders bid was higher than yours, so if they had placed it an hour before yours or a second after yours if it had been placed at 5 seconds before, you would have still lost.
