Subreddit rules check

Can you promote here?
Promotion is allowed only with moderator permission (or inside designated threads). A short, honest modmail before posting costs two minutes and functions as a safe-conduct pass; skipping it is the most common avoidable removal.
From the rules · Top posts almost always use a ‘YSK:’ headline and include a short ‘Why YSK:’ explanation — ask mods before posting promotions or product links.
Links
No explicit link policy. Default to no URL: link-plus-young-account is one of the most common automated removal patterns on Reddit.
What this community rewards
Dominant post formats: guide, news, story
Headline: start with a concise, declarative tip (commonly prefixed with “YSK:”); body: short paragraph (2–6 sentences) ending or including a “Why YSK:” explanation. Use a conversational, practical voice; first-person anecdotes are fine sparingly. What wins: actionable, verifiable, everyday-life tips with brief rationale or sources. Avoid obvious marketing or product pitches unless you first clear it with mods.
Arriving in the local format matters: cross-posting the same text everywhere reads as tourist instantly. The wider method is in the Reddit playbook.
Classified mechanically from the community's published rules and recent top posts, last checked September 2026. Rules change and moderators have the final say: verify at r/youshouldknow's rules page before posting anything that matters.
Thread Otter checks this before every send
These profiles power the product: promo-banned communities never receive a promotional draft, drafts arrive in the local format, and a fact-check gate plus human pacing protect the account doing the talking.
