Yeah, the false positives are annoying, but this is the best balance of speed and accuracy I could think of. The only way to guarantee availability is a WHOIS lookup, which takes 50ms+ per domain, so to check thousands of options would take minutes.
I'm adding a cache of the WHOIS results though, so will hopefully be able to filter a lot more of the false positives from the initial search results in the future.
Actually on a second thought, I think it’s good like this as long as you can check availability on a click, much better it seems to see all domains at once than going on endless pages! Thanks!
