When someone quits facebook, do all their posts disappear or does that happen when someone blocks u?

Recently, a friend's post all disappeared. We've been having weird interactions so I wonder if I was blocked. Or, do posts disappear when someone shuts down their facebook?

Simply click on their name, if it lets you click on it then it will say they have deactivated the account. If you can not click on the name, the person has blocked you.
