How active is r/501c3?
We don't have a reliable posting-rate sample for r/501c3 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/501c3 created?
r/501c3 was founded in September 2015 and is a restricted — approved posters only 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/501c3?
We don't have a promo-tolerance read for r/501c3 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/501c3 for mentions?
Hit Watch on this page. Prowlo starts crawling r/501c3 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/501c3's stats?
Yes. Everything on this page is one MCP tool call away: catalog_get_subreddit returns r/501c3'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.
