how nice of you to not include the domain name so we can verify
this.
as there are many websites created through godaddy by scammers, with stolen credit card, and hidden usually by domainsbyproxy. Investigations into these type operations are lacking.
I worked at GoDaddy for 2 years. I too, have searched a domain name, later to find that someone else had bought it and it was in a parked status.
GoDaddy would never risk their Billions for a Domain name that may be worth hundreds, maybe thousands. It is unethical practices. While I can say that they way they treat their sales reps leaves something to be desired, I do know that they do not monitor and snatch and grab searched domain names. ICANN Monitors for that stuff.
In my case, I actually called the person listed in the WHOIS Information and she was an author. I will not list the domain name here but we had the idea, for the same name, about the same time. She simply beat me to the punch.
I'm afraid you will have to toss this one up to bad luck. It happens. Unless you have proof that GoDaddy is monitoring searched domain names, that is actually quite a BOLD Accusation.
I have searched Domain names that were worth a few thousand dollars, left it alone for 3 or 4 days, and went back and purchased them for the normal $8.99, or whatever it was at that time.
Sorry about your luck. :(
