I have known eudanip for at least 5 years and I am confident to vouch for what he's saying in this comment. Technically, I also admit that it was a breach of the contest regulations, but I also want to point out that it certainly was just a one time slip rather than intentional misconduct. I can see that a lot of people got their submissions nullified, so I hope that the administration team can show understanding towards innocent mistakes like this.
