Super mainstream YT makes a distinction between artistic nudity and just about all websites that revolve around user generated creative content all are similar in this regard.
nsfw needs to be reserved for what I would umbrella under "adult content" sexually suggestive or erotic content. Nudity in and of itself is not erotic or sexually suggestive.
As the admin of OCA, the things I do end up becoming precedent and this is a terrible precedent to set for an art community.
If you want people to actually see your content, it's much less likely they will if it's hidden behind even a single click. Now of course if I thought the content was nsfw I would, but I honestly don't so the only reason I would even consider it is because you asked me to, which is not a reason for me to do something I disagree with. Although I did change the thumbnails a a show of good faith, but at the end of the day, I just simply disagree with you.
