I do think there is at least one compelling argument here which is for the competition having an actual rule or having judges declare their positions ahead of time, would help creators decide whether or not to enter.

I'd be pissed if I entered a contest (and asking for a refund if I paid to enter as this criteria was not disclosed) thinking that I was allowed to make the best game I could make regardless of tech used, only to find out that my max possible score was 66% because shadow judges were biased against me.

It feels like the old reddit moderator meme where the rules are made up and the points don't matter because all it takes is one salty mod.
