The whole point of an LLC is to have limited liability. If you haven't been involved in any fraud or misrepresentation, nobody can go after your assets except in some very specific cases.
You need to speak with your lawyer, or do a little research.
Facebook has progressively and consistently been trying to "slip under the radar" with privacy time and time again. This is not a one time thing, it's a habit and a consistent assault on users. They've never suggested they've ever "gotten" privacy and their flawed assumption that just because i'm on a social network means I want to share everything with everyone is pretty asinine.
I've spent a long time messing with privacy settings and groups and i've never really gotten the results that I wanted. Social networks badly need to start getting the clue that people don't want to give up control over their information. All Facebook needed to do was look at the stories of people who got fired or never hired based on what was on their Facebook to learn this lesson, but they've proven they don't want to do it.
Facebook has gone way off the rails and continues to go off the rails. One wonders whether anyone there is possessed of clue.
