According to GZ Defense site they are closing down the social media platform:

Today we are inactivating the George Zimmerman Legal Case page on Facebook.  We established the page in late April as a companion to the GZlegalcase.com website and @gzlegalcase Twitter account.  On April 28, we published an article called “Why Social Media for George Zimmerman,” where we established seven goals for our digital media presence.  While Facebook helped meet most of these goals during the first three months  of its activation, it has been providing diminishing returns since and has increasingly become a concern to us.  […]

How Facebook Has Not Helped

One of our published goals is Discouraging Speculation, and Facebook, by its nature, does not help us with this goal. Every post made on Facebook becomes an open thread where anyone on the site can comment, and comments inevitably lead to conversations about evidence and speculation about guilt or innocence.  This type of conversation is a natural part of discourse, and there are plenty of places on the Internet where it is appropriate for this to happen, but it need not happen on a page hosted by the defense.

This illustrates our biggest challenge with the page on Facebook: we cannot post without allowing comments.  With comments active, each thread becomes a discussion forum.  While we are not responsible for the comments people leave on our page, because we have the ability to delete comments, what we choose not to delete reflects on the defense team.  Since we can ban users from posting on the page, who we choose not to ban reflects on the defense team.  Admittedly, it does not always reflect well, and that is a concern for the defense.  Because our page on Facebook has already accomplished many of our goals, allowing this concern to exist is not prudent.  (continue reading)
