I contacted them through the website form, and they told me that people who have been disqualified for formatting or late submission have already been notified. People who are disqualified for eligibility reasons will be notified in the future, maybe in February. I assume if they missed a formatting issue and a reviewer notes it, you might still get disqualified, but hopefully then at least you'd get comments.
People on here are sometimes really unpleasant about disqualifications (e.g. "if you can't follow basic formatting instructions, you don't deserve it"). If I were disqualified, I might not want to deal with that on top of rejection, so I bet that's one reason why it's hard to find out when people received notice!
