Certain people just dissapear on facebook, have I been blocked?

Hi, certain people who I have been either friends with or had mutual friends with before just randomly dissapear off my facebook. I cant find them if I search their name, they are not listed under my friends friends list and any photos of them dont have their name in it. Why is this? Have they blocked me? Why would someone just randomly block me for no reason? It cant just be that they unfriended me because they would still show up, is it just some privacy setting or something?

Could be that they changed their privacy settings if you are just a mutual friend of theirs. Or, they could've deleted, Facebook seems to be losing its popularity lately. If they're friendships that matter to you, just ask them off of Facebook! (:

They probably have a privatecy setting or they deleted their account. They might have just made some privacy settings add them if you to see their account or ask mutual friends.
