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 · No advertising outside approved threads; account must be at least 24 hours old to post.
Links
Only specific link types are allowed (docs, papers, non-commercial). Commercial links are removal bait.
What this community rewards
Dominant post formats: story, news, discussion
Headline: short, descriptive tech title (include vendor/feature). Write personal posts in first person; news/discussion can be neutral. Typical length: 150–500 words (short TILs also do well). Tone: professional, practical, slightly snarky. Upvoted: real-world anecdotes, clear troubleshooting steps, security incidents, useful tips. Removed: overt product/service advertising or solicitations.
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/sysadmin'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.
