Thanks for the feedback. I’m really sorry your results were inaccurate.
In about 5% of cases domain lookups are inaccurate, this is the price that is paid for making the search so fast. Of course when you click through to your favorite registrar, it’ll do a full check to ensure availability.
Facebook page availability is also sometimes a problem, it’s impossible to get 100% accuracy there for your search, but Namevine does the best job out of any comparable service.
