Language 3: Objectionable and mature language is permitted. Yes, you can drop the f-bomb occasionally.
Sexual Content 2: Sexual content is permitted. References to sex acts are permitted, but explicit detail is not. Fade to black. You can say it happened, but you can't show it happened.
Violence 2: Moderate graphic violence is permitted. You can say it happened, and you can show a little, but you can't get too gory.
If in doubt, this was taken directly from JCINK's TOS FAQs.
What is considered Mature?
Mature content includes:
---full frontal nudity (typically images/video, though extremely detailed written works could qualify here too),
---graphic sex scenes,
---graphic violence (like detailed torture scenes or body mutilation),
---intense imagery (like surgery),
---full depictions of hard drug use (ex- Cocaine, Heroine, LSD).
For the Terms of Service purposes, it does not matter whether the content is written in story form, a picture, a video clip or an audio track.If you still aren't sure after all that, the answer is probably no.
