The reason is privacy concerns 

Liz, the admonished administrator Kww has been deleting my communication to you on your own talkpage if you haven't noticed. I will not repost it once you tell me it is unwelcome, not him. Again, I saw where you said about me that you "don't understand the reluctance to be forthcoming about alternate accounts." Excuse me if there's a note of frustration in my tone, but *I explained this* in my very first post, and at multiple points in the RFC/U. Once more: I don't have "alternate accounts." I am a single account user with a single prior account that I abandoned for privacy concerns. I hope you will consider going back  and changing your viewpoint. This is Colton Cosmic.
