If your goal is simply to stop seeing someone’s content without them knowing, use or Mute . But if you want a complete, irreversible break—blocking is the nuclear option that definitely unfriends them.
But it goes much further—it makes you invisible, blocks all communication, and erases your friend status permanently until someone proactively sends a new request.
| Action | Unfriends Them? | Can They Find You? | Can They Message You? | Do They Get Notified? | | :--- | :--- | :--- | :--- | :--- | | | Yes | Yes (via search) | Yes (goes to Pending requests) | No | | Block | Yes | No (they cannot search you) | No (messages fail to send) | No |
You suddenly disappear from their friend list.
