Now of course these are great domains and with the way the system works who knows what happened. No doubt domainers called or emailed the whois info on these two domains and tried to work a deal. Maybe that made the registrant renew. Maybe they were just lazy and eventually just renewed.
For the first auction EN.org, someone had over $21,000 tied up on Go Daddy. Of course they are going to get it back, but who wants that hassle ?
In your opinion does Go Daddy need to find a way to improve the system at least on names that go for five figures or more ?
