I wouldn't say you are a thief, as they are your character designs, the fact of the matter is you cannot submit the dolls to your main gallery they must go in scraps as you did not technically draw them yourself, someone else drew them you just put them together, you need to make your own attempts at drawing them without a doll maker and move the doll maker characters into your scraps (you can do this in many ways one would be to go to each submission click edit and change it's category)
I know many other people have not done this, but I just thought as people were being a bit harsh I'd try and explain it, as the simple fact is it's not your art as you did not draw it and you can get yourself in a lot of trouble even ending in a ban from DA, copyright is against the law Gigi but you can simply reverse how much you have annoyed people by doing the right thing and moving it.
