What happens when someone blocks me on Facebook?

[Wayne]

Okay, so I couldn't find her name on the search bar and she didn't appear on my friend's list even after I searched for her.

So I used the direct link, and I got into her profile.

Does this mean she blocked me or what?

I am so confused.
So if I could find her profile and see her profile and add her, does that mean she did not block me, yet there was an Error in Facebook?

When you are blocked you can't;

search them, post on their wall, message them or add them

If you couldn't see her name, it's possible she's either blocked you or she's deleted her Facebook.

Facebook isn't very specific.

It's really these options.
