I read the reactions. In 1 reaction I saw that you can try to contact the one who will get the domain in his account. Check the godaddywhois in a couple of days. If it's European, you should scroll in the whois to the bottom, (the godaddywhois I mean), and you'll find a link where you can send an email to, and you send information like you did in your first post (and maybe or not threaten with making this public or sueing). The mail will arrive in the mailbox of the new owner then (I even think you will see his or her emailaddress). Or maybe suggest buying it at the price, if it seems the person as in an auction fever, like someone suggested and didn't want the domain anyhow and regrets its purchase.
