Somewhat complicated
in short, several of us got a friend request from a Mechanical Spark... so, some of us thought that it was Mech at first... but the only thing that pointed to Mech was the name, the rest was very much unlike him. So, some of us were trying to figure it out, and then this Mechanical Spark person posted a hint on his profile page... which was a "code"... and that "code" was really just a diversion and not a hint whatsoever... and.... skipping to the end, we now know the real identity of Mechanical Spark. Nice job @Beckendorf_Direscope
