Posting rules, in plain words
Self-promotion is judged case by case. Promotion goes in Writing Prompt Wednesday (weekly). Post flair is required.
- Standalone Advertising/Off-site hosting: We do not deny an author's need to promote their work, however we do require this only be done in a relevant context. Any link not otherwise associated with an OC post must have a summary or similar descriptor that fulfils rule #8, providing relevant OC information. Standalone posts which serve only to advertise wares, commercial or non-commercial, will be removed.
- Flair your post: Apply the appropriate [flair](/r/hfy/wiki/ref/guidelines) to your story after posting to make it easier to find certain types of posts. The [bots](https://www.reddit.com/r/HFY/wiki/tools) will not comment if your post does not have the correct flair. If you include the flair in brackets in the title, Automoderator will apply the flair for you.
- Max 4 posts within 24 hours: Limit yourself to posting at most 4 posts within 24 hours of each other to avoid having one author take over the front page. If you are trying to post a single story as multiple parts due to character limits and it would require more than 4 parts, please [message the mods](http://www.reddit.com/message/compose?to=%2Fr%2FHFY) **first** so we can approve it.
Quoted from the community’s own published rules. Always re-read them before posting.
What a good comment looks like here
- — Expresses enthusiasm and appreciation for the story
- — Engages with plot points and character development
- — Offers theories or predictions about future events
- — Uses humor or memes related to the story
- — Acknowledges the author's effort and consistency
- — Provides constructive feedback or asks clarifying questions

r/HFY — frequently asked
How many members does r/HFY have?
r/HFY has 382,810 members as of our most recent crawl on Sep 16. 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/HFY growing?
We don't have 30 days of snapshot history for r/HFY yet, so we're not going to invent a growth number. We've been tracking it since Aug 29; the chart fills in as history accumulates.
How active is r/HFY?
We don't have a reliable posting-rate sample for r/HFY 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/HFY created?
r/HFY was founded in August 2013 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/HFY?
r/HFY publishes 8 rules and 1 of them addresses promotion. The first, “Standalone Advertising/Off-site hosting”, says: We do not deny an author's need to promote their work, however we do require this only be done in a relevant context. Any link not otherwise associated with an OC post must have a summary or similar descriptor that… Read the full rule text on this page and the community's rules page before posting — moderator enforcement is the thing that actually decides.
How do I monitor r/HFY for mentions?
Hit Watch on this page. Prowlo starts crawling r/HFY 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/HFY's stats?
Yes. Everything on this page is one MCP tool call away: catalog_get_subreddit returns r/HFY'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.
