How many members does r/spaceporn have?

r/spaceporn has 4,298,985 members as of our most recent crawl on Aug 11. 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/spaceporn growing?

We don't have 30 days of snapshot history for r/spaceporn yet, so we're not going to invent a growth number. We've been tracking it since Jul 30; the chart fills in as history accumulates.

How active is r/spaceporn?

We don't have a reliable posting-rate sample for r/spaceporn yet. Subscriber count alone is a poor guide to whether a community is active, so treat this one as unverified until the crawl accumulates more.

Can I promote my product in r/spaceporn?

We don't have a promo-tolerance read for r/spaceporn 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.
