1. Don't be an asshole
2. Don't do illegal stuff
3. Only upload either artwork you've made yourself or artwork made by an artist that has already uploaded artwork to this site.
This is to limit the scope of this booru to a more "casual doodle" friendly environment instead of opening the floodgates to the wealth of existing artwork out there (especially if it's already in another booru out there). This is not a place to "collect random porn". It's a place to store your own silly doodles (or finished pieces), be they NSFW or not, and be able to easily tag and share them around.
4. Tag the artist when you upload images!
4.1 If you upload art of another artist
You must apply a tag of theirs!
4.2 If you are the artist
It's not the end of the world, as you will appear as the uploader for that image, but if you don't have at least one artist tag associated with your art then other people will not be allowed to upload your art here. This is to avoid wrongly uploading doodles against the wishes of artists outside the booru. If you want to be in control of all the artworks that are uploaded here of you as an artist you can create an artist tag in the following format:
artist:DNP:artist-nameThis lets others know not to upload images with that tag, only you as the artist themself will be allowed to post with that tag.
DNP stands for `Do Not Post`, and is reserved for the artist / owner of the artwork to let others know that they are not allowed to post artwork by that artist. It's very easy to check the uploader against the artist tag to see if you're breaking this rule. This is to let artists that perhaps only want to upload some of their artwork here, but not all, or if they just don't feel comfortable about having other random people upload art and tag it as theirs.
