r/IBO — frequently asked

How many members does r/IBO have?

r/IBO has 182,867 members as of our most recent crawl on Aug 27. 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/IBO growing?

Over the last ≈28 days r/IBO changed by +2.3% — a gain of 4.1K 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/IBO?

We don't have a reliable posting-rate sample for r/IBO 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/IBO?

We don't have a promo-tolerance read for r/IBO 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/IBO for mentions?

Hit Watch on this page. Prowlo starts crawling r/IBO 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/IBO's stats?

Yes. Everything on this page is one MCP tool call away: catalog_get_subreddit returns r/IBO'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.
