Well your accusation that it was me that created that other username I don't take lightly.  This board is anonymous in some aspects and users that create multiple accounts should be called out.   You not allowing mods to support verification that this is your only username, while I offer to allow a mod/admin to verify it really speaks about you that something is fishy. 

Now, could I at least get the admin/mod to confirm/deny that the username KimJung-il (not me, the troll one that was created) is you? And if there are multiple other account that post in threads about XSPEC that are linked to you?

You're avoiding this like the plague.     You're fooling no one.
