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.
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, discussion, question
Use a short, descriptive title — often first-person (“I made…”) or a concise technical phrase. Post an image/animation with a brief explanatory caption or link to a demo. Tone is enthusiastic and nerdy; top posts are visual math/plots or simulations with a short technical note. What gets upvoted: striking visuals, interesting math, reproducible demos; avoid off-topic/irrelevant images.
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 October 2026. Rules change and moderators have the final say: verify at r/mathpics'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.
