WordPress doesn’t discriminate between Turks and Arabs!

Turk equals Arabs or is it the turbaned avatar?

Why does WordPress think that I’d like to become the master of my domain by registering mechanicalarabs.com? What’s the relationship between Mechanical Turk and Mechanical Arabs? Is it because of the¬†turbaned¬†anthropomorphic automaton engraving I use as my avatar? That supposedly mechanical chess player is known as the Turk. Can someone please explain?!
