r/hoi4 — frequently asked
How many members does r/hoi4 have?
r/hoi4 has 505,106 members as of our most recent crawl on Sep 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/hoi4 growing?
Over the last ≈24 days r/hoi4 changed by +0.5% — a gain of 2.6K 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/hoi4?
We don't have a reliable posting-rate sample for r/hoi4 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/hoi4 created?
r/hoi4 was founded in January 2014 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/hoi4?
We don't have a promo-tolerance read for r/hoi4 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/hoi4 for mentions?
Hit Watch on this page. Prowlo starts crawling r/hoi4 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/hoi4's stats?
Yes. Everything on this page is one MCP tool call away: catalog_get_subreddit returns r/hoi4'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.
