A while back I came across some of my archives that mentioned a BBS name that was popular in the past. Thinking it would be neat to own the domain name of the company that went out of business, I went to GoDaddy and checked. It was available awesome. Got distracted, came back an hour later and it was no longer available, but was at auction.
My first suspicion is nothing nefarious happened. I could have misread available vs auction, but I don't think so. I might have mistyped the domain name, but I don't think so. Something didn't feel right.
A few days later I checked another domain using whois through icaan. No resolution. Available. Pop over to GoDaddy and do the same thing ... check name is available. As a test, I wait an hour and come back to the name at auction.
I cannot explain what happened it except maybe GoDaddy's name check leaks or someone had the exact same name ideas when I had them. Again, this was years ago and am unsure if it still occurs.
