What a repost is

Reposting — formerly called crossposting — shares an existing Reddit post into another community. The new post embeds a preview of the original, including the original username, source community, and score, so readers can reach the source while discussing it in the new room.

Reddit Help’s best-practice line is simple: only repost content that is relevant to the destination. Random spreads across unrelated communities can look like spam and reflect poorly on you and the source community.

Who can receive a repost

Not every community accepts reposted content. If a community disallows it, that option is greyed out in the community picker. That is a destination setting, not a bug in your account.

Greyed-out destination = that community blocks reposts. Pick another room or ask the mods whether a native post (not a repost) is welcome — and read their rules first.

Repost on reddit.com

  1. Open the original post.
  2. Click Repost under the post.
  3. Choose the target community in Select a community.
  4. Edit the title if needed, add flair if the destination requires it, then click Post.

Repost on iOS and Android

  1. Open the original post.
  2. Tap the Repost control under the post.
  3. On iOS, pick the community from the list or search; on Android, choose community or profile in the Post to menu.
  4. Edit the title or add flair if needed, then tap Post.

Share a comment as a post

You can share a comment into a community as its own post where the destination allows it. On web or apps: open the comment’s overflow menu, choose Share as post, pick a community, optionally edit the title/body, then Post.

Moderator Help for bringing content into a community notes that sharing comments as posts needs links enabled in that community’s Post & Comments settings — if Share as post is missing, the destination may have links limited.

Relevance checklist

  • Would this community’s regulars care about this specific post — or am I farming exposure?
  • Does the destination allow reposts (not greyed out)?
  • Have I read the destination rules for title format, flair, and spoilers?
  • Should the title be rewritten so it makes sense without the source context?
  • If I moderate a community and I am reposting outward for growth, am I still staying relevant and non-spammy?

Hypothetical: a detailed trail report fits both a regional hiking room and a gear room. Repost once into the second room with a title that names the gear angle, rather than blasting five loosely related communities.
