What actually happened to Nobody Else? (Theory)

This is in the perspective of Neptune_Ninja_Comics

The theory
The mystery user is known as "Nobody_Else" was a trivia generation commenter who lasted about 5 months, and was a big part of GC history, including the Comment Dryspell. He was banned numerous times on GC, but still continued to come back.

But why did he just disappear one day?

He just disappeared around August, never to be seen again.

I theorize that he probably was banned for good from GC, but that doesn't explain why he left the wiki too..

The answers
There are three possible answers.

3. He is CD51

2. He figured if he got banned from GC for good, why not just leave the wiki?
 * 1) He just felt like leaving without an explanation. (Or because of Super not wanting him to know he left)

The actual Answer
(Still unknown)

It is assumed however that he just left without feeling the need to tell anyone.
