Well, you see, even if you have a painting marked mature and censored will not grant you full immunity to the reasons why Collecting Smiles AB took it down. the reasons are either: Posting unlawful, abusive, harmful, or obscene content of any kind and Posting por.nographic content or images that depict se.x organs. There is a fine line to what is considered appropriate levels what is considered to have been marked as mature. "NSFW" content is clearly not one of them. So remember you are bound by the terms of agreements and you should be fine.
