Creators take a lot of pride in their work, so that's why we do not steal, take credit for, or upload someone else's creation as our own with little to no changes. Respect creators, and give credit for using their creations. It is just common sense, and common courtesy to not steal.
Theft and re-uploading without credit is becoming a big issue in the community. Please keep an eye out for creators if you see their creations uploaded by someone else.
