Some thoughts about this:
1)
More entries than normal: Did Anonymous submission really caused new entries? We have only three first timers. Another (supposed) author (Almighty Zael) is an old member who was inactive and returned. Three others (Captain of the Guard, Osahon and Bradley) made their debut on Pirates and Gem_Cutter on Potions, none of which were compulsory anonymous submissions nor they debuted as Anonymous and there were other debuts who actually didn't enter Corpses.
I credit new blood income more with
@Mr.J on Twitter (and others retweeting) than Anonymous submission. We really didn't have much propaganda before, did we? I think it would be interesting to know data of debuts before and after Twitter. Maybe I'm wrong, but that's the impression I have.
The Contest Twitter started on June and the number of entries on our current year:
January (4th wall) - 18 entries
February (Fanfic) - 13 entries
March (Nightmares) - 14 entries
April (Dystopia) - 13 entries
May (Fairy Tale) - 11 entries
June (Wikipedia Article) - 12 entries
July (Story Generator) - 13 entries
August (Potions) - 18 entries
September (Pirates) - 17 entries
October (Corpses) - 22 entries

We are not discussing stories or writing: As you can see from my detective posts, me and others are clearly enjoying the guessing game.
But that didn't stop me from noticing a very big difference from previous months: we are discussing guesses and possible author names. No one is talking anything about any story or about the writing. Ironically, only Nora actually did - and to point out stories that were not hers.
Contrast that to other months, or even the 1750 Contest. Nora posted a story and right away Gem_Cutter came and commented on it, and now Lordoftheword too.
Now on Corpses we got to the point we can't even say how we liked a certain story or anything about any story "to not influence anyone on anything". I mean, seriously? So it's not only bias some people think it's going around, but that we are also that susceptible to vote or not on stories because of praise or comments of others in the Discussion or Voting thread?
I'm having fun playing Sherlock, but for me there is also a lot of fussiness and other un-fun stuff going on as well.
^This. Once again, I can speak from my experience as a new guy to these forums. I felt "safe" and "comfortable" posting my story here anonymously, because I knew that if I didn't perform or I churned out pure garbage, there wouldn't be eye rolls or otherwise pointed in my direction. Now that I've witnessed the people of integrity on these forums it seems funny that I thought that, but think about when you showed someone (best friend, girlfriend/boyfriend...mom) your first piece of writing. Were you afraid? Were you nervous? Hell yes, you were.
Anyway, it's pretty obvious where I stand. But I'll compete and comment and love this contest no matter what, so however we come to a consensus I'm 100% in. 
That's quite a curious post, Lord!
You introduced yourself pretty clearly, you are Dustin Bilyk and you have a book called
Tournament of Hearts: The Librarian Gladiator. You even have a picture on Amazon! You certainly didn't look like a shy type!
I mean, it's kinda of funny you want anonymity for your virtual nickname you just created to stand in front of your real one! It's like a triple secret identity!
I can understand being a bit cautious before exploring the ambient, but now I'm also curious how you deal with a bad review and stuff like that

Regarding bias:
I'm not gonna post too much regarding this today, but will tomorrow. Probably. I also need to sleep. Anyway...
I think people are using the word "bias" here too widely and even incorrectly. Bias (in this case) is an unfair judgment from the get go, that you simply refuse to believe a new entry can have the same quality as an entry of an old member.
I'm just gonna say there are a lot of people who have been around here for years and only recently got their first win, don't win for a long time or still have to win for the first time.
And a lot of veteran members who alternate doing well in one contest and not too great in the next one.
For me this is proof enough.
"If I have to chose between two stories, and one is from a known member and the other is not, I will most likely consider the person. That's bias!"
No, it's not. First you are assuming everyone has the same line of thinking, same preferences and will all arrive at the same conclusion, which is false.
The fact you are having difficulty in choosing between a veteran and a newbie already proves you gave equal consideration to both and that you are not biased.
If an older member gave for you a slight tip in the balance for the final choice, it still not bias. A story is entertainment for someone and members and their interactions are also part of that entertainment.
On prized contests, you don't know who or how many entered and don't interact with anyone involved. There's also a Committee who doesn't know anyone either and choose the winners. That's not the case here.
And if it were a publisher, if there's one book spot and they have two similar books and one is from John Doe and the other from Joe Abercrombie, guess who is more likely to bite the dust?
Again: Check voting threads and the fact veteran members who only recently got a first win, don't win for a long time or never won at all. This is fact, not hypothesis.
Also, personal preference is a lot different than bias and plays a tremendous influence on anyone's choices. Before we even get to authors, there are styles, tropes, sub-genres and elements used on the stories.
Some people always love comedic stories and always vote for it, while they never have any appeal for others. Some people clearly don't like dark and violent stories, while for others it's their primary preference. Is it bias against certain styles and elements used in a story? No, it's personal preference, and that's the difference.
Maybe people who want their names published should contact Xiagan and Anonymous entries should be default, simply because it's easier for a newbie who just joined and is not familiar with the forum tools and mods. It's also easier for Xiagan to put their names if they ask "hey, I want my name, why my story is Anonymous?" than they trying to figure out they need to contact a mod and there are Anonymous subs.
Anyway, for me people are trying to fix what is not broken, placing mountains where there were none before.
