r/ufo — frequently asked
How many members does r/ufo have?
r/ufo has 436,485 members as of our most recent crawl on Oct 17. 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/ufo growing?
We don't have 30 days of snapshot history for r/ufo yet, so we're not going to invent a growth number. We've been tracking it since Oct 17; the chart fills in as history accumulates.
How active is r/ufo?
Around 11.1 posts per day, measured from the newest 100 posts on Reddit, which span 8.9 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/ufo created?
r/ufo 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.
Who posts in r/ufo?
Of the last 100 posts we sampled, 80% came from distinct accounts; the newest was published Oct 17. 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/ufo?
We don't have a promo-tolerance read for r/ufo 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/ufo for mentions?
Hit Watch on this page. Prowlo starts crawling r/ufo 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/ufo's stats?
Yes. Everything on this page is one MCP tool call away: catalog_get_subreddit returns r/ufo'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.
