Judge decisions are posted publicly and can be read by anyone. The way the decision for that mix plays out can easily be interpreted as a discouragement of pure chiptunes to be submitted; not that it necessarily is, just that it can easily be read that way. You really don't have to stretch that far to get that conclusion, especially based on my own vote, which was basically a NO vote on technical grounds (i.e. "no because I based on other decisions we don't accept chiptunes"). Incidentally, that was a bad vote on my part.
If the entire crux of your argument here is "I don't understand how ANYONE could think that!" then you need to take a step back and realize that people are going to interpret things in different ways.
You have to remember, this was like 5+ years ago. I'm not trying to get all "you're just a kid on you" because that's dumb and irrelevant, but you really were not around on OCR back then and kind of lack the context of the mindset and feel of the site.
Espergirl wasn't rejected on compositional grounds (although that probably should have been the reason it was NO'd, IMO), so to call it out as being "composer-wank" (to borrow the term you borrowed from me ) in the context of discussion why it was rejected is silly.
A little more reading, a little less posting, bro.
