Subreddit rules check

Can you promote here?
The written rules take no clear position, which is NOT permission: unclear communities enforce norms through removals instead of rulebooks. Sort by top, study which builder posts survived and how they were framed, and when in doubt ask the mods.
From the rules · No subreddit rules were visible; if you plan to post your own product/resource, ask the moderators first to avoid potential self-promo issues.
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: question, guide, discussion
Title = a concise technical question or request (’Can X...?’, ‘How to...’, ‘Suggestions for...’). Write in first person, short-to-medium length, formal/academic tone. Provide definitions, assumptions, equations or proof sketch in the body. High-quality textbook/resource shares, clear worked examples, and precise questions get upvoted; vague, low-effort, or off-topic posts are ignored.
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/probabilitytheory'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.
