Read from r/sysadmin’s published rules on Mar 12. Communities change their rules without notice and enforce requirements (karma, account age, flair) that may live in the sidebar or automod rather than here — the source page is the authority.

r/sysadmin — frequently asked
How many members does r/sysadmin have?
r/sysadmin has 1,329,788 members as of our most recent crawl on Oct 12. Prowlo re-checks tracked communities on a rolling schedule, so this figure moves rather than sitting frozen at whatever it was when a scraper last ran.
Is r/sysadmin growing?
Over the last ≈33 days r/sysadmin changed by +0.8% — a gain of 10K members. We compare against the nearest snapshot we actually hold and state the real span rather than rounding it to a clean "30 days".
How active is r/sysadmin?
We don't have a reliable posting-rate sample for r/sysadmin yet. Subscriber count alone is a poor guide to whether a community is active, so treat this one as unverified until the next sample lands.
When was r/sysadmin created?
r/sysadmin was founded in October 2008 and is a public — anyone can post community. Age matters: an older community with steady growth has survived Reddit's moderation churn; a young one with a spike may not.
Can I promote my product in r/sysadmin?
r/sysadmin publishes 5 rules and 1 of them addresses promotion. The first, “Advertising”, says: * The reddit advertising system exists for this purpose. Invest in either a promoted post, or sidebar ad space. * Vendors are free to discuss their product in the context of an existing discussion. * Posting articles… Read the full rule text on this page and the community's rules page before posting — moderator enforcement is the thing that actually decides.
How do I monitor r/sysadmin for mentions?
Hit Watch on this page. Prowlo starts crawling r/sysadmin into your Dataset — every new post indexed and embedded, searchable semantically, queryable by your AI agent over MCP, and able to trigger keyword alerts in Slack. Prowlo is read-only; it never posts on your behalf.
Can my AI agent read r/sysadmin's stats?
Yes. Everything on this page is one MCP tool call away: catalog_get_subreddit returns r/sysadmin's members, growth, promo tolerance and similar communities as typed JSON — free, no credits. Connect your agent to api.prowlo.com/mcp and it can vet the community and start watching it in the same conversation.
