In this case, a GoDaddy employee was bidding on their own domain auctions. They're allowed to use the "buy it now" and buy closeout domains, just not allowed to bid on the godaddy main auctions.
Not really, it happened to me two weeks back. The domain I searched for on GoDaddy was not available after 2 hours and when I did a who is look up it was registered by Synergy Wholesale Pty Ltd another registrar.
My suspect is that there could be some triggers that would go off based on the domain name you search and other parameters and then if its something they are interested in then it could probably automatically register it or send it to another registrar for registration via an api or something.
Of course it not stopped, it is still happening and not only with mentioned registrar, one should never check potential good domains using godaddy and similar sites without buying it straight away, otherwise you might lose it or be scammed by having to buy it on higher price.
Odds are that you got fucked by passivedns, not godaddy.
I think it’s less of a problem now though. All of the valuable namespace is either in use or squatted already.
cat /tmp/wants.txt | while read d; do echo -n $d:; dig $d in ns | grep '>>HEADER<<' | awk '{print $6}'; done
You get NXDOMAIN if it doesn't exist. That doesn't necessarily mean you can register it though. Maybe it's expired but in the grace period, or some other kind of exits-but-disabled state. If it does exist it might be for sale. Anyway, for quickly checking what's probably unregistered from the shell this one liner works great. A whois query usually takes about a second. Dig takes about a tenth of a second, and DNS queries aren't rate limited like WHOIS.
You can make these queries via a trusted registrar, and the domains you query won’t be broadcast to the world in cleartext.
