Subreddit guides combine public Reddit source URLs, captured rules, visible verification dates, and Rankhog's account-safety workflow.

Rule summary

  • Don’t be dick or mods will smesh: Follow Reddiquette, don't be a jerk.
  • Don't ask for or offer medical or legal advice: Go see an appropriate professional concerning medical and legal issues. This includes asking others to share their experiences as this always elicits medical advice. Also includes any sort of skin conditions, infections, injury recovery, etc.
  • No pirated content or any buy/sell type content, copyright rules: Don’t share pirated content such as ripped PPV streams, torrents, or instructional videos. Do not ask for links to this content or otherwise imply in any way that you are going to be illegally acquiring material. Also please do not offer to buy or sell anything in the sub, be that training gear, instructionals or anything else. Finally, any posts violating copyright rules will be removed.
  • No spam, including your own content: websites, videos, apps, AI slop, "market research", etc.: If you are an active member participating in discussions, occasional or even regular posting of your content is fine, especially if it provides value to the community. If most of your posts/comments are promoting your own content, it may get removed. No AI-generated content and no bots. No "market research" style posts. This community does not exist to help you develop your app/website/brand.
  • Videos must be of/about BJJ: Match videos for analysis, tutorial/instructional videos, and other videos about the sport of BJJ are welcome any time. Other content is at mods' discretion. Spam rules apply. Short-form and other promotional type video content must have value to the community in and of itself.
  • No social media posts about non-BJJ topics: Posts which contain social media content not directly related to BJJ will be removed. Please do not bring social media drama into /r/bjj. Just because it involves a BJJ athlete or community member does not make it related to BJJ.
  • Use the appropriate megathread for common/beginner questions/posts: Sunday: Promotion Party Monday: Strength & Conditioning Tuesday: Tournament Tuesday Friday: Open Mat - (Almost) Anything Goes Week-Long Fundamentals Thread for beginner questions
  • Memes/Shitposts are heavily restricted: Please see r/bjjmemes, r/jiujitsumemes and r/rollsomememes instead. Shitposts/follow up shitposts may only be posted on Sundays. "Follow-up Shitposts" must follow these rules: They must be tagged as "Follow-up Shitpost" They must link to the original post at the TOP of the post body. There may only be a single "Follow-up Shitpost" per original post. There is a difference between a ‘shitpost’ and a ‘shit post’. We reserve the right to remove the latter at our discretion.
  • Use [Spoiler] in your title: Use [Spoiler] in your title when posting BJJ or MMA match results within 24 hours of the event.
  • Mods' discretion is king: Sometimes content may not fall cleanly under a particular rule, and sometimes rules are not always enforced with equal strictness. Mods may exercise discretion to remove or allow content in order to promote the kind of environment we want /r/BJJ to be. This includes determining what is and is not appropriate topical matter for the subreddit.
  • Sexual assault: This conversation will be heavily moderated. Anything resembling victim blaming, cheap jokes, or insensitive and thoughtless remarks will be deleted and you'll be banned. For those who have had similar experiences, [you can call, text, or online chat for support from anywhere in the world, 24/7](https://share.google/YLeFmQB6ZAQxdoOsE) We believe Hannah Griffith, and we stand with her and all others who have been assaulted by those from this sport we love.
  • generic dear diary: As you can imagine, we cannot act as the stream-of-consciousness blog of out many members.

Works well

  • A detailed technique breakdown or written analysis of a common BJJ problem that is genuinely useful on its own
  • A tutorial video about an actual technique or drill that teaches something without asking anyone to click away or buy anything
  • A thoughtful comment history followed by an occasional original post about training or the sport, with no link attached
  • Answering beginner questions inside the week-long fundamentals thread to build real standing in the community
  • A match analysis post with a spoiler tag in the title if it is within 24 hours of the event
  • Sharing your own honest training experience inside the Friday open mat megathread instead of a standalone post

Avoid

  • Promoting your website, video, app, or brand, especially if most of your posts and comments link back to it
  • Posting anything AI-generated, including AI written advice or AI made videos
  • Framing a survey or feedback thread around your product as market research
  • Asking or answering anything medical, like mat rash questions or injury recovery timelines
  • Sharing or requesting pirated streams, torrents, or instructional videos
  • Buying, selling, or trading gear or instructionals inside the sub outside the megathreads or Etsy order flow mentioned in the community survey thread rules if they exist here, since rule 3 only allows the megathread exception it names explicitly, which for r/bjj is none outside its own stickied threads, so simply treat buy and sell content as banned

What r/bjj Is For

This is the community for Brazilian Jiu-Jitsu. The public description says it covers training, techniques, news, competition, asking questions and getting advice. Beginners are welcome and discussion is encouraged. So the room is full of people who train, coach, compete, or are thinking about starting, and they are here to talk about the sport itself. The rules make it obvious the moderators want conversation between real members, not broadcasts. Weekly megathreads handle the everyday stuff like promotions, strength and conditioning, tournaments, open mat stories, and beginner questions. If your product or service has something to do with training, competing, or running a gym, this is a place where practitioners hang out, but only as a participant first.

Rules That Matter Before Posting

The one that decides your fate as a founder is “No spam, including your own content: websites, videos, apps, AI slop, 'market research', etc.”. It says clearly that if you are an active member participating in discussions, occasional or even regular posting of your own content is fine, especially if it provides value. It also says the community does not exist to help you develop your app, website, or brand. Rule “Don’t be dick or mods will smesh” is the baseline civility rule. “Don’t ask for or offer medical or legal advice” matters because injury and skin questions get shut down fast, and asking people to share experiences counts as seeking advice. “No pirated content or any buy/sell type content, copyright rules” bans streams, torrents, instructional rips, and any buying or selling. “Videos must be of/about BJJ” lets tutorial and analysis content in, but short form and promotional video must provide value to the community in and of itself. “Use the appropriate megathread for common/beginner questions/posts” funnels beginners, training updates, and casual chatter into weekly threads. “Memes/Shitposts are heavily restricted” keeps jokes to Sundays and points people to meme subreddits. “No social media posts about non-BJJ topics” blocks drama and off topic posts. Finally “Mods' discretion is king” means even content that slips through a gap in the rules can still be removed.

What To Post

The path here is participation first. Read and comment on technique and competition threads for a while before you post anything of your own. When you do post, the rule about spam gives you the actual test, your content has to provide value to the community in and of itself. A tutorial video or a written breakdown of a technique that stands on its own, without needing a signup or a purchase to be useful, fits. A plain link to your site does not, because links are banned in posts. If you have a genuine training story or a beginner question, use the week-long fundamentals thread or the Friday open mat thread instead of a new post. Save training updates for the megathreads. If you want to share something you made, like a tool or a write-up, be ready to answer questions and take part in the discussion it creates, and keep your overall ratio of promotion to normal participation heavily tilted toward normal participation.

What To Avoid

Do not post your website, video, app, or brand as a standalone promo. Do not post market research style threads. Do not post AI-generated content or run bots here. Do not use links, they are banned in posts. Do not ask or offer medical or legal advice, including injury recovery and skin conditions, even as a question about what others experienced. Do not share or request pirated content like ripped streams or instructionals. Do not buy or sell anything in the sub. Do not bring social media drama or non-BJJ topics into the sub. Do not post memes or shitposts outside of Sundays, and follow the exact tagging and linking rules if you do post a follow-up shitpost. Do not post diary style stream of consciousness posts about your day. Do not post match results without a spoiler tag in the title if the event is within 24 hours. Do not ignore the megathreads. And never be a jerk, because the mods say they will smesh.

Common questions about r/bjj

Can I post a link to my own site or tool here?

Yes, but conditionally. You need to be an active member participating in discussions, your promotion must be occasional, and your content must provide value in itself.

Can I introduce myself and my product in one post?

A first post with a link is risky. Better to join discussions for a while first, then contribute content that stands on its own.

Can I ask for feedback on my idea?

Post the question itself if you have it. Beginners are welcome and the description explicitly invites questions and advice.

Where do beginner questions go?

Yes, every week. Monday for strength and conditioning, Tuesday for tournaments, Friday for open mat style anything goes chat, plus a week long fundamentals thread for beginners.

Can I post a meme about my product?

Only on Sundays. Tag it correctly, and a follow up shitpost must link the original at the top of the post body.
