How can you tell if someone blocked you, or deleted their facebook?

[Ateneinten]

What are differences?

[Kieran]

you will not be able to find them!
try getting someone else/ another account to search them.
dont forget the person you are trying to find may have deactivated there account or changed privicy settings. so if deactivated wont be visible to anyone blocked will just be invisable too you

If they deactivated their facebook they will still appear on your friends list just without a picture. If they blocked you you wont be able to find them at all. You can also check by going on somebodys account that is not blocked by the other user.
