if i unfriend someone on facebook are they notified

If you unfriend someone on Facebook, they are not directly notified by Facebook about it. The platform does not send any official alert or notification when someone is unfriended. However, the person may realize they have been unfriended through indirect signs such as no longer seeing your posts, not being able to interact with your profile as before, or noticing your absence from their friends list if they check manually. Third-party apps claiming to notify users about unfriending exist but are not official and come with privacy and accuracy concerns. In summary, no direct notification is sent for unfriending on Facebook, but the action might become apparent through changes in social interactions or profile visibility.
