The reason could be directly the name itself : Secde.
I mean sec.de is also a great domain hack if you would think in Turkish.
(Read the meaning of sajda, sajdah, secde here).
You know that over 2 millions Turks are living in Germany. Since "secde" is such an important word in Islamic-Turkish world they might have bought it. Conspiracy, yes, but still a possibility. Wanted to share.
