r/aliens — frequently asked
How many members does r/aliens have?
r/aliens has 1,606,938 members as of our most recent crawl on Oct 13. 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/aliens growing?
Over the last ≈34 days r/aliens changed by +3.5% — a gain of 55K 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/aliens?
Around 25.4 posts per day, measured from the newest 100 posts on Reddit, which span 3.9 days. Posting rate matters more than subscriber count when you're deciding where to spend your time — it determines how long your comment stays visible.
When was r/aliens created?
r/aliens was founded in August 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.
Who posts in r/aliens?
Of the last 100 posts we sampled, 82% came from distinct accounts; the newest was published Oct 13. A low share means a feed dominated by a handful of accounts (bots, mods, or one prolific poster) rather than a community.
Can I promote my product in r/aliens?
We don't have a promo-tolerance read for r/aliens yet. Default to the safe approach: read the sidebar rules, contribute in threads where you gain nothing, and mention your product only when it is the honest answer to someone's question.
How do I monitor r/aliens for mentions?
Hit Watch on this page. Prowlo starts crawling r/aliens 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/aliens's stats?
Yes. Everything on this page is one MCP tool call away: catalog_get_subreddit returns r/aliens'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.
