How to block someone on Reddit
You can block another Reddit user directly from their profile or from a comment or post they made. Once blocked, that person cannot send you direct messages, see your profile, or view your posts and comments — though they can still see your public content if they are logged out or use a different account. Blocking is one-way: the blocked person will not be notified, and you will not see their username, posts, or comments anywhere on Reddit.
Reddit's block feature works differently depending on whether you are using the website, the official mobile app, or a third-party app. The steps are straightforward on all platforms, but the exact location of the block button varies slightly.
Key Takeaways
- Blocking someone on Reddit prevents them from messaging you and hides their posts and comments from your feed, but does not prevent them from viewing your public profile if they log out.
- You can block a user from their profile page, from any comment or post they made, or from a direct message conversation.
- The blocked person will not receive a notification that you blocked them, and you will not see any indication that they tried to contact you.
- If someone is harassing you across multiple accounts, you may need to block each account separately, and Reddit's report tool can escalate serious violations to moderators or Reddit staff.
Blocking from a user's profile on desktop or mobile
The most direct way to block someone is to visit their profile. On the desktop website, go to the person's profile by clicking their username anywhere on Reddit. In the top right corner of their profile header, you will see three dots (the "more options" menu). Click those dots and select "Block user" from the dropdown menu.
On the official Reddit mobile app (iOS or Android), tap the person's username to open their profile. Tap the three dots in the top right corner of the screen, then tap "Block user." A confirmation message will appear asking if you are sure — tap "Block" again to confirm.
Blocking from a comment or post
You do not have to visit someone's full profile to block them. If you see a comment or post from someone you want to block, you can block them directly from that content. On desktop, hover over or click the three dots next to their username on the comment or post, then select "Block user."
On mobile, tap the three dots next to the person's username on their comment or post, then tap "Block user." This method is faster if you are scrolling through your feed and encounter someone you want to block without leaving the page.
Blocking someone who messaged you
If someone sends you a direct message that you want to block, open the conversation. On desktop, click the three dots in the top right corner of the message thread and select "Block user." On mobile, tap the three dots at the top of the conversation and select "Block user."
Blocking someone from a direct message conversation will prevent them from sending you future messages, but the conversation history will remain in your inbox unless you delete it manually. You can delete the conversation by opening it and selecting "Delete conversation" from the options menu.
What happens after you block someone
Once you block someone, their posts and comments will no longer appear in your feed, in search results, or in subreddit threads you are viewing. If you are already in a conversation with them in a comment thread, their comments will appear as "[deleted]" or "[removed]" to you, depending on whether they deleted the comment themselves or a moderator removed it.
The blocked person cannot send you direct messages, and any messages they try to send will fail silently — they will not receive an error message, but the message will not reach you. They also cannot see your profile, your posts, or your comments when they are logged in. However, if they log out of their account or use a different account, they can still see your public posts and profile information.
Reddit does not notify the blocked person that you blocked them. They may realize it if they try to message you or visit your profile and see an error, but there is no explicit notification from Reddit.
Unblocking someone if you change your mind
If you want to unblock someone later, go to your Reddit settings. On desktop, click your profile icon in the top right corner, select "Settings," then scroll down to "Safety and Privacy." Under "Blocked Users," you will see a list of everyone you have blocked. Click the "Unblock" button next to their name.
On mobile, tap your profile icon, then tap "Settings." Scroll to "Safety and Privacy" and tap "Blocked Users." Tap "Unblock" next to the person's name. Unblocking is when ready and will restore their ability to message you and see your profile.
When blocking is not enough
Blocking prevents someone from contacting you directly, but it does not stop them from creating new accounts to harass you or from discussing you in other subreddits. If someone is harassing you across multiple accounts or in public posts, use Reddit's report tool instead of or in addition to blocking.
Click the three dots on a post or comment and select "Report." Choose "Harassment" or "Threatening violence" depending on what the content is, and provide details about what is happening. Reddit's Trust and Safety team reviews reports of coordinated harassment and can take action against accounts that violate the site's rules. For severe cases — threats, doxxing, or coordinated campaigns — you can also report to Reddit directly through the report form at reddit.com/report.
Frequently Asked Questions
Can someone tell if I blocked them on Reddit?
Reddit does not send a notification when you block someone. However, they may figure it out if they try to visit your profile or send you a message and encounter an error. There is no way for them to see a list of people who blocked them.
If I block someone, can they still see my old posts?
If they are logged out or using a different account, yes — they can still see your public posts and profile. Blocking only hides your content from them when they are logged into the account you blocked. Your posts in private subreddits or your profile settings that restrict visibility will still be hidden.
What if someone keeps harassing me with new accounts?
Block each new account as it appears, and report the behavior to Reddit using the report tool. Mention in your report that the person is using multiple accounts to evade a previous block. Reddit can investigate patterns of harassment and suspend accounts that violate the harassment policy.
Does blocking someone remove their past comments from threads I am in?
No. Their old comments will still be visible in threads, but they will appear hidden or collapsed to you depending on your settings. You can manually collapse or hide individual comments if you do not want to see them.
Can I block a subreddit instead of a person?
Reddit does not have a built-in block feature for subreddits, but you can mute or leave a subreddit. On desktop, visit the subreddit and click "Mute" in the sidebar. On mobile, tap the three dots at the top of the subreddit and select "Mute subreddit." Muted subreddits will not appear in your home feed, though you can still visit them if you search for them directly.
