The designs I submitted is my own work. I'm a designer and I learn by seeing the things. If an architect sees a building and design the same building that doesn't mean that he is stealing his work. He is just using his ideas. That's what we all designer do. I have many accounts in many websites with different names. Here I'm Micro Ice, in some other website I'm something else. But that doesn't mean that I'm submitting some other work. The work I have submitted was mine.
If you see your entries, entry no #609 and #261 are the design of woozeedesigns. The entry no #792 is same as the entries of woozeedesigns but there he just change the colorful circular ring into a square. Did logobrands steal the design of woozeedesigns?
No, he just uses the ideas of his and create some thing new. And who know these two are same or different.
Before giving any one warning, Just cross check clearly.
