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 · Do not post ID requests, surveys/polls, or medical questions; remember to apply the correct link flair and avoid repetitive/link-spam.
Links
The rules clearly allow links. A plain-text mention still often outperforms a URL from a young account.
What this community rewards
Dominant post formats: showcase, news, discussion
Short, descriptive headline (curiosity-driven). Post in first person or neutral voice with a one-sentence hook + a striking image/video or reputable link. Keep body brief; cite sources for research/news. Upvoted: cool microscopy, animals, recent papers, clear questions. Removed: ID requests, medical questions, surveys, low-effort reposts or spam.
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 July 2026. Rules change and moderators have the final say: verify at r/biology'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.
