Can you crosspost a skeet to Reddit? Here is the real answer.

! Reddit has strict subreddit rules about self-promotion and external links

+ ! Most subreddits do not allow posting Bluesky links directly

+ ! Reddit's crossposting feature is only for sharing Reddit content between subreddits

+ ! Content format mismatch: skeets are micro-content, Reddit rewards long-form text

= too much manual work

↓ There's an easier way

What You Need to Know

01

How Bluesky creators share content in relevant subreddits

The approach that works: take the idea from your skeet and expand it into a proper Reddit text post — with context, background, and a genuine angle for that specific subreddit.

Do not just paste a Bluesky link.

For creators using Bluesky to discuss topics that map to specific subreddits (tech, journalism, photography, politics), the skeet is the rough draft — the Reddit post is the full write-up.

Check each subreddit's rules before posting.

Most communities have specific guidelines about links and self-promotion.

02

Writing a Reddit post that does not read like a skeet

Reddit communities are text-first and discussion-oriented.

A post needs a clear title (under 300 characters, but use the full space), a detailed body that adds context, and a question or angle that invites genuine responses.

The 10% rule on many subreddits means only 10% of your posts should be self-promotional.

If your Bluesky content is about a topic, not about you, lead with the topic.

On Reddit, the substance drives karma — not the platform you came from.

03
