Do to a rash of people posting poser freebies without checking the links/thumbnails to make sure there working properly, Any freebie posted that has a Invalid Thumbnail will be Denied as of today, I had to edit 7 freebies today because of invalid thumbnail links to them, And I will no longer be doing this. The Freebie Preview is there for a reason when uploading freebies, so that you can verify that the freebie is working properly. So use it, make sure the file link and the thumbnail you supply are Valid before submitting.
