Devious Journal Entry

So I had to remove one of my BG Manipulation from Deviantart because one of Deviantart members assumed that my BG was a Painting and Said i was infringing on copyright act! Well I wasnt infringing on any Copyright act because that BG was made up of more than one images, that are not copyrighted, and are free, which I used to create a scene! I cant understand why is it that some people would assume without proof that another member stock is illegal to post here! Because I cant bother with the hassle of trying to prove that I made this BG, Upon request from my friends I pulled it from my BG album!  Every time I post stuff here I am always wondering who will comment next to say that My stuff was not legit! Yikes this is really getting retarded because I try my best to stick to the Deviant art rules! I guess when a artist gets many comments on a manipulation there will always be someone out there who will try to ruin someone's day!
