How can you block a friend who deactivates their profile and activates again only to surf your page Because you said yes to being friends that person can now see your account?

To block a friend who frequently deactivates and reactivates their profile, go to your privacy settings and adjust who can see your profile or posts. You can also directly block the person, which will prevent them from viewing your account entirely, regardless of their account status. Additionally, consider adjusting your friend settings to limit visibility for certain friends or non-friends. Remember, blocking is a permanent solution; if you wish to reconnect later, you will need to send a new friend request.
