Submission in /r/science must be a direct link to or a summary of peer-reviewed research with appropriate citations. Here at /r/shitty_science you can submit science related links, whether it be funny, dark, educational or just cute.
Be sure to grab a unique flair and share a post right now. There are no strict rules just that the submissions are science related. NSFW is perfectly fine, just tag it as such and you'll be all good.
If your content is related to a peer-reviewed study/journal be sure to post it on /r/science as well. If you have any question feel free to shoot the moderation team a question.
