What it tells me is that they're just poor words for business use. Most tld's - if registered - aren't developed, there's not a single .ca in use using the word scarce or liquorice in it (as far as I know).
In google adwords, if you had a big fat wallet and wanted to buy ads on the term "scarce", even on a "broad match" basis, you'd be able to buy precisely Zero clicks per month.
With Liquorice (which isn't the preferred north american spelling) you could buy 2.5 clicks per month.
So if you're looking for blame, look to the left of the dot, not the right
