As long as posts comply with the rules it's fine.
You might want to create a page with the set of rules first 
Any feedback is greatly appreciated and I will try to integrate any wanted feature.
Suggestions:- It would be nice to have a warning for NSFW section.
- Increase its loading speed.
- A report button.
I like how it allows us to up/downvote each tag separately...
- Has potential.
The rules are on the upload page which you can see when logged in, I might create a seperate page for that soon where you don't need to be logged in.
You have to manually click on the NSFW filter which even says that it's NSFW, I guess thats warning enough..? Not sure though.
I'm actually creating a report function for posts and comments right now!
Thanks for your feedback.
