How to Block Someone on Reddit: What It Does and What to Expect

Blocking someone on Reddit is one of the platform's most direct privacy tools — but it works differently than many users expect, and the experience varies depending on your device, Reddit version, and how you use the platform. Here's a clear breakdown of what blocking actually does, how to do it, and what factors shape the outcome.

What Blocking Someone on Reddit Actually Does

When you block a Reddit user, you create a mutual visibility barrier. Blocking prevents the blocked user from sending you direct messages or chat requests. Depending on your Reddit version, it may also filter out their comments and posts from your view.

It's worth understanding that Reddit's block feature is not a full content shield in the way blocking works on platforms like Instagram or Twitter/X. The blocked user can still see your public posts and comments — they just lose the ability to contact you directly. Your public activity on subreddits remains visible to anyone, including people you've blocked.

This distinction matters. If your concern is harassment via DMs, blocking is highly effective. If your concern is someone monitoring your public Reddit activity, blocking alone won't address that.

How to Block Someone on Reddit (By Platform)

🖥️ On Desktop (Reddit.com)

1. Navigate to the profile of the user you want to block
2. Click the three-dot menu (⋮) on their profile page
3. Select "Block Account"
4. Confirm the action

Alternatively, if someone has sent you a message:

1. Open the message in your Inbox
2. Click "Block user" directly from the message thread

📱 On the Reddit Mobile App (iOS and Android)

1. Tap the username of the person you want to block
2. Tap the three-dot menu in the top-right corner of their profile
3. Select "Block Account"

The steps are nearly identical on both iOS and Android versions of the official Reddit app. Third-party Reddit apps (such as those built on the Reddit API) may place this option in different menus, but the underlying account action is the same.

Through a Message or Comment

If you're viewing a comment and want to block that commenter:

1. Tap or click the username
2. Follow the profile block steps above

Reddit does not currently offer a one-tap "block from comment" shortcut — you always route through the user profile or message inbox.

What Changes After You Block Someone

This table reflects general platform behavior. Reddit has been gradually updating its blocking system, and older Reddit versions (including some third-party clients) may show different behavior than newer builds.

Variables That Affect Your Experience

Several factors determine what blocking actually looks like in practice:

Reddit version. Reddit has rolled out an improved block system in newer versions of its app and website that does more to filter out blocked users' content from your feeds. If you're on an older version or a cached interface, you may not see the same filtering behavior.

New Reddit vs. Old Reddit. Users who prefer old.reddit.com may notice differences in where blocking settings live and how thoroughly blocked content is hidden. The classic interface has fewer dynamic content filters.

Third-party apps. Apps like Apollo (discontinued), Relay, or Boost implement Reddit's API features but handle display filtering differently. Blocking still registers at the account level, but visual suppression of content depends on how the app renders it.

Subreddit context. In active subreddit threads, you and a blocked user may still appear in the same comment section. Reddit doesn't remove their comments from threads — it may just collapse or hide them depending on your app version.

Moderator accounts. If the person you've blocked is a moderator of a subreddit you participate in, their moderation actions (removals, bans) still apply to you. Blocking a moderator does not exempt you from their role in that community.

Managing Your Block List

You can view and manage everyone you've blocked through Reddit Settings:

• On desktop: Settings → Privacy & Safety → Blocked Accounts
• On mobile: Profile icon → Settings → Privacy → Blocked Accounts

From here you can unblock users. Once unblocked, the person regains the ability to message you, and any content filtering tied to the block is removed.

Reddit does not notify users when they are blocked or unblocked.

The Spectrum of Situations Blocking Addresses

Blocking lands differently depending on your situation:

• If you're dealing with repeated unwanted DMs, blocking is straightforward and effective — it cuts off that channel immediately.
• If you want to avoid seeing someone's comments in a subreddit, blocking helps in newer Reddit versions but may not fully suppress content in older interfaces.
• If you're concerned about someone tracking your activity, blocking doesn't prevent that — Reddit profiles are public by default.
• If the issue involves rule-breaking behavior, Reddit also allows you to report users, which is a separate action from blocking and routes the issue to moderators or Reddit's Trust & Safety team.

Some users combine blocking with muting (which stops notifications from a user without fully blocking them) depending on the level of separation they need.

What works best depends on what you're actually trying to solve — and whether your primary concern is contact, visibility, content filtering, or something else entirely. The right combination of Reddit's privacy tools shifts based on that.
