but on patreon it says and i qoute :
" You can post nude creations on Patreon of both real and fictional subjects. Posts with mature themes should be marked as “Patron Only”. This means that you cannot post nudity in public areas including your profile picture, banner, reward images or ‘about me’ section.
As a reminder, you should never post or share nude creations of any individual under the age of 18, including yourself. As a strong commitment to child safety, we will work with law enforcement whenever we come across child exploitation material. You can read more about our pornography policy in the next section.
Lastly, we understand that you may make a mix 18+ creations and other types of creations, and that is okay with us too. We will always review your work within its context. However, if you have concerns, please let us know and we will provide you with guidance on how to maintain a dual presence. "
EDIT:
Oh i just saw that this only means nudity not pornographic content. Sorry
But that is some conflicting messages they give to their community, and i don't understand why they would go for exactly these rules.
