Rules can change, so Rankhog keeps verification dates and the original public Reddit sources visible.

Rule summary

  • Posts must be maps: All submissions must be map(s). Anything else should go into the weekly discussion thread.
  • No Low Effort Memes: Low effort memes are not allowed.
  • Must meet aesthetic standards: Read [this link](https://web.archive.org/web/20200315090526/http://mapporn.org/2020/02/08/towards-a-mapporn-aesthetic/) for more information.
  • No Advertising: No Advertising
  • No Repost Bots: No Repost Bots

Works well

  • A single high resolution image of an original map you or your team made, posted with no pitch
  • A visually striking map of real data, like population, terrain, or history, that tells a story on its own
  • A beautifully designed map related to your industry, shared purely as a contribution with no product mention
  • Non-map questions or discussion topics placed in the weekly discussion thread instead of the feed

Avoid

  • Any post that promotes your product, service, or company, banned under “No Advertising”
  • Posting charts, screenshots, infographics, or photos, because “Posts must be maps” removes anything else
  • Map memes or joke images, removed under “No Low Effort Memes”
  • Low quality or visually sloppy maps, removed under “Must meet aesthetic standards”
  • Reposting old popular maps through automation, banned under “No Repost Bots”

What r/MapPorn Is For

This community is for high quality images of maps, and that is really the whole brief. The public description is just that one line, and the rules back it up. People post here to look at beautiful, interesting, or well made maps. The name is a play on a genre of image subreddits, so the room expects visual quality first and conversation second. If your post is not a map, the rules say it belongs in the weekly discussion thread instead. The people posting are map lovers, cartography hobbyists, and curious browsers who upvote images that look good and teach them something about the world.

Rules That Matter Before Posting

Four rules decide whether a marketing-adjacent post survives here. “Posts must be maps” is the gatekeeper, because anything that is not a map gets removed and should go to the weekly discussion thread. “No Advertising” is the one that ends most founder plans, since advertising is simply not allowed with no exceptions listed. “Must meet aesthetic standards” means even a genuine map can be removed if it looks bad, and the rule points to a published guide on the community's aesthetic. “No Low Effort Memes” closes the loophole of dressing up a joke as content. “No Repost Bots” matters if you ever automate posting, because repost bots are banned outright.

What To Post

If you are a founder, the honest answer is that you post maps here, not products. A good post is a single high quality image of a map that stands on its own, something genuinely interesting to look at and clearly made with care. If your work connects to maps, like a mapping tool or a data product, the respectful play is to share a beautiful map your tool helped create, with no pitch, no call to action, and no link in the post pushing people to buy anything. Let the map be interesting and let curious people ask questions in the comments. Anything that is not a map, like a question or a discussion topic, goes in the weekly discussion thread. Since I have no observed top posts for this community, I would study what is currently on the front page before posting and match that level of polish.

What To Avoid

Do not advertise, because “No Advertising” bans it outright and there is no soft version of it here. Do not post anything that is not a map, because “Posts must be maps” sends everything else to the weekly discussion thread. Do not post low effort memes, because “No Low Effort Memes” removes them. Do not post a map that looks sloppy, because “Must meet aesthetic standards” gives moderators grounds to remove even real maps that fall short. And do not use repost bots or recycled content, because “No Repost Bots” is a rule here.

Common questions about r/MapPorn

Can I post a map that includes my company logo?

The rules do not carve out an exception, and “No Advertising” bans advertising outright, so I would not risk it. Post the map clean.

Can I ask for feedback on my mapping project here?

Not in the main feed, because “Posts must be maps” sends anything that is not a map to the weekly discussion thread, and a feedback request is not a map image.

Can I link to my blog post that contains a map?

The rules do not say anything specific about links, but “No Advertising” bans advertising, so a link that promotes your site is risky. A plain map image with no pitch is the safe shape.

Is a funny map meme okay if it is about maps?

No. “No Low Effort Memes” removes them regardless of the topic.

My map is real but not very pretty. Will it survive?

Probably not. “Must meet aesthetic standards” lets moderators remove maps that fall short, so polish it first or post elsewhere.
