I joined designcrowd as a designer and I've had all my designs rejected by the Quality Team. Poor design or execution or some nonsense like that. All I know is that these people steal designs, tell you it got rejected and tell you to design a new one, steal that one too and give the clients the sloppiest ones while keeping the logos to be recycled later. Why do you think they explicitly state that no watermarks are allowed? Absolutely scam of a website. Stay away for your sanity.
