You may notice that posts from new Bluesky accounts appear more frequently in your feeds and notifications. This is by design. Bluesky applies a temporary visibility boost to new accounts to help them gain initial followers and engagement. This article explains the technical mechanism behind this algorithm bias, how long it lasts, and what you can do to manage its effects on your experience.
Key Takeaways: Bluesky’s New-Account Boost in the Feed Algorithm
- Algorithm boost duration: The visibility boost lasts approximately 30 days from account creation.
- Feed ranking signal: Account age is a direct weight in the recommendation engine, not a separate queue.
- Settings > Moderation > Muted Words & Users: Use these tools to reduce unwanted new-account posts in your feeds.
Why Bluesky Gives New Accounts a Visibility Boost
Bluesky uses a personalized recommendation algorithm to determine which posts appear in the Discover feed and in notifications. One of the signals the algorithm considers is account age. A newly created account receives a temporary positive weight in the ranking calculation. This weight decays over time, typically over the first 30 days. The goal is to solve the cold-start problem, where new users see little engagement because they have no followers. By boosting their posts, Bluesky helps these accounts get noticed and begin building a network.
The boost is not a separate feed or list. It is a hidden score modifier applied inside the same algorithm that ranks all posts. The exact weight and decay curve are not publicly documented, but the effect is observable: posts from accounts less than a month old appear in your feed more often than posts from older accounts with similar engagement metrics.
Bluesky’s algorithm also considers recency, your past interactions, and the network of who you follow. The new-account boost is one of several factors. It does not override relevance entirely, but it does increase the probability that a new account’s post will be shown to a wider audience.
How the Boost Affects Your Feed and Notifications
The boost applies to two main areas of Bluesky: the Discover feed and notification suggestions. In the Discover feed, you may see posts from accounts you do not follow that were created recently. In notifications, you may receive more follow requests or quote posts from new accounts. The effect is strongest in the first week of the account’s existence and gradually declines.
The boost does not apply to the Following feed, which shows only posts from accounts you explicitly follow. If you want to avoid new-account content entirely, switch to the Following feed. The Discover feed is where the algorithm’s bias is most visible.
Duration of the Boost
Based on user observation and developer discussions, the boost lasts approximately 30 days. After this period, the account is treated like any other account of the same age. The algorithm no longer adds extra weight to its posts. If the account has not gained followers or engagement during the boost, its posts will receive less visibility going forward.
Managing the Algorithm Bias in Your Feed
You cannot disable the new-account boost entirely, but you can reduce its impact on your experience. The following steps show how to control what appears in your feeds.
- Switch to the Following feed
Tap the feed selector at the top of the home screen. Choose “Following” instead of “Discover.” This feed shows only posts from accounts you follow. It ignores the algorithm’s new-account boost entirely. - Mute specific new accounts
When you see a post from a new account you do not want to see, click the three-dot menu on the post. Select “Mute account.” This removes all future posts from that account from your feeds and notifications. - Use Muted Words to filter topics
Go to Settings > Moderation > Muted Words. Add words or phrases commonly used by new accounts that you want to hide. Posts containing those words will not appear in your feeds. - Create a custom feed with stricter ranking
Use a third-party tool like SkyFeed or Bluesky Feed Creator to build a feed that ranks posts by engagement rate or account age. This lets you exclude new accounts entirely. Add the custom feed to your home screen. - Report spam or policy violations
If a new account is posting spam or abusive content, click the three-dot menu and select “Report.” Bluesky can remove the account and its posts from the network, which also removes them from your feed.
Common Misconceptions About the New-Account Boost
“The boost gives new accounts an unfair advantage in all feeds”
The boost only applies to algorithmically ranked feeds, primarily Discover and notifications. The Following feed is chronological and does not use the boost. If you only use the Following feed, you will not see any effect from the algorithm bias.
“The boost lasts forever if the account stays active”
The boost is time-limited. It decays over approximately 30 days regardless of activity. After that, the account’s posts compete on equal footing with all other accounts of the same age.
“You can remove the boost by changing your account settings”
There is no user-facing setting to disable the new-account boost. It is a server-side algorithm parameter. The only way to avoid its effect is to use the Following feed or mute individual accounts.
Bluesky New-Account Boost vs Other Social Platforms
| Item | Bluesky | Mastodon | X (Twitter) |
|---|---|---|---|
| Boost type | Temporary weight in recommendation algorithm | No new-account boost; chronological feed by default | Temporary reach boost for new accounts in For You feed |
| Duration | Approximately 30 days | Not applicable | Approximately 30 days |
| User control | Switch to Following feed or mute accounts | Not needed; feed is chronological | Switch to Following feed or mute accounts |
| Transparency | Not publicly documented | Open source; algorithm is visible | Not publicly documented |
If the Boost Is Causing Problems in Your Experience
“I see too many spam posts from new accounts”
Spam accounts often exploit the new-account boost. Report these accounts using the three-dot menu. Bluesky’s moderation team can remove them. You can also mute the account or use Muted Words to hide common spam phrases.
“My own new account is not getting enough visibility”
The boost is automatic. If you are not seeing engagement, check that you are posting original content and using relevant hashtags. The boost increases the chance of being seen, but it does not guarantee engagement. Engage with other accounts by replying and reposting to build a network.
“The boost makes the Discover feed useless”
If the Discover feed feels cluttered with new-account posts, switch to the Following feed for a cleaner experience. You can also create a custom feed that filters by account age or engagement rate. This gives you full control over what you see.
Conclusion
Bluesky’s algorithm bias toward new accounts is a temporary visibility boost that lasts roughly 30 days. It helps new users get noticed but can make the Discover feed feel less relevant. You can manage this by switching to the Following feed, muting individual accounts, or using Muted Words in Settings > Moderation. For more control, create a custom feed that excludes new accounts. The boost is not a permanent feature and decays naturally over time.
