If someone has deleted their Facebook account, you will no longer be able to find them on the platform or access their profile. If you were friends with that person on Facebook, their profile and any previous interactions with them will also be removed from your account.
If someone has blocked you on Facebook, you may notice several signs that indicate you have been blocked. These include:
You can no longer find the person's profile when you search for them on Facebook
You cannot send messages or friend requests to the person
You cannot see any posts or comments the person has made on other people's profiles or pages
You may receive an error message when you try to visit the person's profile or access their content
Keep in mind that there are other reasons why you may not be able to access someone's profile, such as if they have deactivated their account or if there are technical issues with the platform. If you suspect that someone has blocked you or deleted their account, it's best to reach out to them through other means, such as email or phone, to confirm.
