My entry was eliminated inmediately

Hi! Well my problem is that I decided to design a logo for a contest. In the contest it says that theres 2 days left for applying. I submit my design, upload an image and choose the option to submit it. The problem is that when i press submit, in like 5 or 8 seconds, inmediately gives me a message "Your entry #256 in Dotego was eliminated". Well i think that the server is denying my logo? Because i dont think that the creator of the contest had seen my logo in 5 seconds and eliminated. I think this is some kind of bug, because i also think my logo violate the Design Contest rules or copyright.
