No, hacked is when someone steals an Ebay account that isn’t used much or hasn’t been used in a while, and bids on expensive items with it. Of course, they have no intention of paying for the item; it’s not even their account. They just do it to mess with Windstone (and other sellers), and to try to make their sales invalid.
Sniped is when a real buyer outbids everyone at the last few seconds of the auction.
