Hi lacrossevet, all of the designs that were removed from your contest were removed -- like Loquaz said -- because the designers who submitted them used clipart or artwork from another source that they did not create. This not only violates the submission rules at LT, but it also violates copyright laws. And if your winning design included clipart, you would not be able to trademark your logo.
Going forward, you can either choose from among the remaining designs or extend your contest. If you wish to extend, please contact customer service at support@logotournament.com.
