Whatever you just typed made little to no sense at all. I'm guessing you're saying that because no one else uploaded stolen material that it makes it alright for you? Wrong.
The case is not closed by the way, there never was one. Just you stealing photographs of topdown cars, editing out the road/ground beneath them, uploading them, and then claiming them to be completely made of your hand, no tracing, no using other people's photos.
Hm... And that you it have achieved? But these sprites are more similar to the present cars. The theme is closed. Heh! Its car exists no only this site...
