Will it let you upload an "updated" file?
I was just thinking of your removal problem. Will NG still allow you to "update" your submission? Go to your account > Portal Submissions > Kanzeni Marin Nitsuite/Edit Submission. Try uploading a blank .swf file, or maybe a small .swf file that explains why you had to remove the submission from NG (since it looks like people still aren't reading your description). The NG staff might then delete it entirely, but I don't think it'd be grounds for any disciplinary action. Either way, your problem is solved.
