I’m wondering exactly how blocking on Facebook works. Say I block a user.

As I understand it, it means I don’t see any posts from the blocked person anywhere on Facebook and they cannot see mine. But does that mean that said person can still post on fan pages that I manage and I just don’t see his/her messages? That seems to be the case and I don’t love that. If I block someone and they post something inflammatory on my business page wall or something, I’d like to at least know so that I can delete it. Or better yet, I’d like to be able to stop her from posting on pages I manage entirely. Is there a way to do that?

As for profiles, it seems that pre-blocking, an exchange on someone else’s wall that looked like this:

My Friend #1: It was nice to see Hillary today.
Me: Nice to see you too!
Person: Hillary is a jerk!
My Friend #2: You are the jerk!

Now will just look like this after I block the person:

My Friend #1: It was nice to see Hillary today.
Me: Nice to see you too!
My Friend #2: You are the jerk!

Leaving me confused and never knowing that someone said something about me. Part of me likes this because it lets me just check out of the drama entirely but the other part of me feels like this allows the other people wide open to publicly attack me and I would never know I was even being attacked to report them to Facebook.

If it seems like I’m being paranoid, that is simply because a person I blocked recently is highly mentally unstable and I’m concerned about exactly what this person can and cannot do after being blocked. I am especially concerned about how it works on a Facebook fan page. There is a very high risk of this person trying to post things on my Page and I have no way of knowing if they do so.

Facebook’s official word on this doesn’t give me any more info:

A block prevents specific people from viewing your profile. Any ties you currently have with the people you block will be broken (friendship connections, friend details, etc.). Your profile will not be visible to them and you will not appear in their search results or friend lists. Blocking is mutual, so they will also become invisible to you as well.

Keep in mind that blocking someone may not prevent all communications and interactions in third-party applications, and does not extend to elsewhere on the Internet.

Please note that removing a block will not restore a connection. If you block a friend and then remove that person from you Block List, you will need to send them a new friend request.

But it also says here:

Blocking allows you to prevent most interactions with someone on Facebook. People you block won’t be able to find you in searches, view your profile, or contact you with pokes, Wall posts, or personal messages. In addition, they will not be able to see your Wall posts, comments on mutual friends’ Walls, or that you are a member of the same group as them.

They will, however, see your comments on content that is posted by a mutual friend. You will see their comments as well.

But this isn’t true. Conversations on the walls of mutual friends where this person had posted a comment are now simply not showing that person’s comments as illustrated above. So I am really confused.

Anyone with any experience with this that can share your thoughts would be very appreciated!
