r/longevity — frequently asked
How many members does r/longevity have?
r/longevity has 211,775 members as of our most recent crawl on Aug 18. 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/longevity growing?
We don't have 30 days of snapshot history for r/longevity yet, so we're not going to invent a growth number. We've been tracking it since Aug 18; the chart fills in as history accumulates.
How active is r/longevity?
We don't have a reliable posting-rate sample for r/longevity 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.
Can I promote my product in r/longevity?
We don't have a promo-tolerance read for r/longevity 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/longevity for mentions?
Hit Watch on this page. Prowlo starts crawling r/longevity 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/longevity's stats?
Yes. Everything on this page is one MCP tool call away: catalog_get_subreddit returns r/longevity'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.
