Sure thing, I really appreciate your site by the way! There actually are services that list good available domain names already but they all want to sell you the list before you can even know if their list is any good, so I've never bothered.

As for extra-small, I used Google Domains to check it, it certainly seems to be registered as of May 16th.

I did some more digging, it appears that namecheap (or another registrar/reseller) squatted it and is reselling it as a premium domain for $190.

I suppose in the most technical sense, it is available, but my assumption was that this was a list of unregistered domains rather than say an AfterNIC competitor. Would it be possible to note in your database which domains are unregistered and which are being scalped?
