Rules can change, so Rankhog keeps verification dates and the original public Reddit sources visible.

Rule summary

  • Always link to the original source.: We require that all submitted links be the original source of the information; whether it's a blog post, conference presentation, paper, video, mailing list item, etc. The only exceptions made are for content that is hosted on sites like YouTube or SlideShare, or if the original source is no longer available online. » [More details](https://www.reddit.com/r/netsec/wiki/guidelines#wiki__always_link_to_the_original_source)
  • Titles should provide context.: Submission titles should give a brief bit of context for readers; being terse yet informative is ideal. » [More details](https://www.reddit.com/r/netsec/wiki/guidelines#wiki__titles_should_provide_context)
  • Check the new queue for duplicates.: To avoid being flooded with news-of-the-week style stories, we remove links to subject matter that has already had recent coverage in the subreddit; should a new article be submitted which adds significant depth to the analysis, reach out to us - we're often willing to make exceptions for high quality content. » [More details](https://www.reddit.com/r/netsec/wiki/guidelines#wiki__check_the_new_queue_for_duplicates)
  • Commercial advertisement is discouraged.: Our subscribers are here for interesting technical content, not to line your wallet. We don't allow the posting of commercial content unless the submitting user has both a preexisting relationship with our community, and a personal stake in its success. If you have not been submitting quality content or comments to /r/netsec for 6+ months and have had a minimal number of removed submissions, you should refrain from posting links to commercial services or products.
  • Don't create unnecessary conflict: Discussions should remain polite and civil; any hostility toward other users is likely to draw the ire of the moderators and a sharp rap from the banhammer.
  • No prohibited content or sources: /r/netsec requires that all posts be technical in nature and high quality. Multiple topics and sources are not permitted to be submitted due to conflicts with this requirement; our fulltext list of prohibited topics and sources, linked below, provides more details. » [More details](https://www.reddit.com/r/netsec/wiki/betaguidelines#wiki_prohibited_content)
  • No low-quality or political posts: Submissions that are low quality or political in nature (instead of technical) are not permitted on /r/netsec and are subject to moderation.
  • No tool posts: We do not accept links to tool/exploit code or READMEs - please post these in the monthly discussion/tool thread instead. We do accept links to quality technical posts explaining what is innovative about a tool.
  • No AI-generated posts: LLM-generated posts are not welcome

Works well

  • A link to an original research paper or conference presentation on a security topic, with a title that gives brief context.
  • A link to a quality technical blog post that explains what is innovative about a security tool, rather than a link to the tool itself.
  • A link to an original mailing list item or video that provides technical security value, with a terse and informative title.
  • A commercial link posted only after six or more months of quality submissions and comments, from an account with a minimal number of removed submissions.

Avoid

  • Do not post links to tools, exploit code, or READMEs, as the "No tool posts" rule sends those to the monthly thread.
  • Do not submit AI-generated posts, because the "No AI-generated posts" rule bans them entirely.
  • Do not post commercial content unless your account has at least six months of quality history here, since the "Commercial advertisement is discouraged." rule requires a preexisting relationship.
  • Do not submit links that are not the original source, because the "Always link to the original source." rule allows no exceptions except for sites like YouTube or SlideShare.
  • Do not post low-quality or political content, as the "No low-quality or political posts" rule removes it.

What r/netsec Is For

This community is a curated aggregator of technical information security content. The people who post here are security practitioners, students, researchers, and hackers. The mission, as the description says, is to extract signal from the noise and provide value to people who care about security. The content is meant to be technical and high quality.

Rules That Matter Before Posting

The rule that decides whether your post survives is "Always link to the original source.", which requires every submitted link to be the original source of the information. The "Commercial advertisement is discouraged." rule is the one that decides whether a marketing-adjacent post lives or dies, because it bars commercial content unless you have a preexisting relationship with the community and a personal stake in its success. The "No tool posts" rule sends tool and exploit code links to the monthly discussion thread. The "No AI-generated posts" rule bans LLM-generated posts outright. The "Check the new queue for duplicates." rule removes links to subject matter that has already had recent coverage. The "No low-quality or political posts" rule removes anything that is not technical and high quality.

What To Post

A good post here is a link to the original source of technical security content, with a title that gives brief context and is terse yet informative. If you are a founder doing respectful Reddit marketing, you should only post commercial content after you have spent at least six months submitting quality content and comments to this community with a minimal number of removed submissions. If you have a new tool, do not link to it directly, but you can link to a quality technical post that explains what is innovative about it.

What To Avoid

Avoid posting anything that is not technical and high quality, because the "No low-quality or political posts" rule removes it. Avoid tool links and exploit code, because the "No tool posts" rule sends those to the monthly thread. Avoid AI-generated posts, because the "No AI-generated posts" rule bans them. Avoid commercial content if you are new, because the "Commercial advertisement is discouraged." rule blocks it unless you have six or more months of quality history here. Avoid duplicate topics, because the "Check the new queue for duplicates." rule removes them. Avoid hostility, because the "Don't create unnecessary conflict" rule brings out the banhammer.

Can I share a link to a new security tool I built?

No, the "No tool posts" rule says to post tool links and exploit code in the monthly discussion thread instead.

Are AI-generated posts allowed?

No, the "No AI-generated posts" rule states that LLM-generated posts are not welcome.

You should check the new queue first, because the "Check the new queue for duplicates." rule removes links to subject matter that has already had recent coverage.

No, the "No low-quality or political posts" rule removes submissions that are political instead of technical.
