How to Block People You May Know on Facebook

Facebook's "People You May Know" feature is designed to help you expand your network — but not every suggestion is welcome. Whether it's an ex, a coworker you'd rather avoid, or simply someone you don't want connected to your account, Facebook gives you options to manage these suggestions. The catch is that "blocking" this feature works differently depending on what outcome you actually want.

What "People You May Know" Actually Is

Before diving into the steps, it helps to understand what's driving those suggestions. Facebook's algorithm surfaces potential connections based on several signals:

  • Mutual friends — the most common trigger
  • Shared networks — schools, workplaces, or locations you've listed
  • Uploaded contact lists — if someone has your number in their phone and shared contacts with Facebook
  • Profile interactions — viewing someone's profile, being tagged in the same posts, or attending the same events

This matters because blocking a suggestion and preventing future suggestions are two different things. One is a one-time action; the other requires understanding why Facebook keeps showing that person.

How to Remove a Suggestion from People You May Know

Removing a specific person from your suggestions is straightforward on both mobile and desktop.

On Mobile (iOS or Android)

  1. Open the Facebook app and tap the Friends icon (the person silhouette) at the bottom or top of the screen
  2. Scroll to the People You May Know section
  3. Find the person you want to remove
  4. Tap the X or Remove button next to their name
  5. Confirm if prompted

On Desktop

  1. Go to facebook.com and click Friends in the left sidebar
  2. Navigate to People You May Know
  3. Click the X next to the person's name to dismiss the suggestion

This removes that person from your current list, but it doesn't guarantee they won't reappear — especially if the underlying signal (like a mutual friend) gets stronger over time.

How to Block Someone on Facebook Entirely 🚫

If you want to go further — preventing someone from seeing your profile, messaging you, or appearing in your feed — a full block is the appropriate step.

To Block Someone

  1. Go to the person's Facebook profile
  2. Click or tap the three-dot menu (⋯) on their profile
  3. Select Block
  4. Confirm the action

When you block someone:

  • They can no longer find your profile in search
  • They can no longer see content you post
  • Any existing friend connection is removed
  • They won't appear in your People You May Know — and you won't appear in theirs

This is the most complete way to eliminate someone from your Facebook experience, including removing them as a suggestion.

Reducing How Often Suggestions Appear Overall

If the issue isn't one specific person but the feature itself, a few settings adjustments can reduce how aggressively Facebook surfaces suggestions.

Review Your Connected Information

  • Remove your phone number or email from your profile if you've shared it — Facebook uses this to match you with people who have your contact info
  • Audit your workplace and school listings — shared networks are a major suggestion driver
  • Check your privacy settings under Settings > Privacy > How People Find and Contact You — restricting who can look you up using your contact details reduces the matching pool

Don't Sync Your Contacts

If you've previously allowed Facebook to upload your phone contacts, you can manage this:

  1. Go to Settings & Privacy > Settings
  2. Search for Upload Contacts or navigate to Your Facebook Information
  3. Remove uploaded contacts if applicable

This won't erase past matches but limits future ones.

The Difference Between Removing, Unfriending, and Blocking

These three actions are often confused, and choosing the wrong one produces unexpected results:

ActionRemoves SuggestionRemoves Friend ConnectionPrevents Profile VisibilityPrevents Messaging
Remove from list✅ (temporarily)
UnfriendPartial
Block✅ (permanently)

Unfriending someone who is already a friend removes the connection but leaves both profiles visible to each other. They may still appear in People You May Know afterward — sometimes more frequently, since a newly removed connection is still a recent mutual signal.

Blocking is the only option that comprehensively removes someone from your Facebook experience in all directions.

Why the Same Person Keeps Reappearing

This is a common frustration. Even after removing a suggestion, some people keep coming back. The reasons vary:

  • A new mutual friend was added
  • The person viewed your profile (Facebook doesn't confirm this publicly, but interactions influence the algorithm)
  • A shared group or event created a new connection signal
  • Facebook refreshed its matching based on updated contact data

In these cases, removing the suggestion repeatedly is only a temporary fix. A full block — or adjusting the underlying profile and privacy settings — addresses the root cause more durably.

What Varies by User Situation

How much control you actually have over People You May Know depends on factors specific to your account setup:

  • How much personal information is public on your profile — more visibility means more matching signals
  • How many mutual connections you share with frequent suggestions
  • Whether you've synced contacts in the past and whether those uploads persist
  • Your account's age and activity level — older, more active accounts have richer social graphs for the algorithm to draw from

Someone with a tightly locked-down profile, no synced contacts, and few mutual friends will see far fewer unwanted suggestions than someone with an open, well-connected account. The right combination of actions — removing, blocking, or adjusting privacy settings — depends on which of those factors applies to your specific situation.
