What is the best Facebook security setting to keep kids out of "grown up" postings?

Honestly, I would ignore all friend requests from people you don’t want seeing your posts, and make sure that all of your posts are family-friendly.

Why kids are on Facebook I’ll never understand, but so are bosses and grandparents, so we all need to accept that we’re a lot more out there than we ever were.

I know this is not answering your question at all, but you can change all of your settings to only allow certain groups (i.e adult friends) to see things, but I’m not sure you can preclude groups. Play around with privacy settings, and make sure nothing is visible beyond “Friends of Friends” or even “Friends,” then set exceptions for your photos.

Here’s why it barely matters: if someone has tagged you in one of their pictures, it’s still visible even if your name’s not on it. This is why we all have to grow up.

Sorry for the rant, I had a long conversation about employers on Facebook this week when I said I didn’t want to become a fan of my company.

Put them on a separate friend list, limit what they can see, and don’t allow their posts to show up in your feed. Sometimes it’s good for you to have an idea as to what the kiddies are up to, without having to live with it.

Put them in a separate friend list, as @PandoraBoxx said. Every post you make, you can choose the privacy settings. For the ones you don’t want them to see, edit the privacy settings on it before you click the Post button.

@Mamradpivo There’s a privacy setting that lets you prevent people from tagging you. And even if you don’t enable that, you can always untag yourself.

When you make a posting, you can use the “Hide this from” feature, and just enter in their category name.

Follow these steps:
“Privacy -> Customize -> Make this visible to (friends you want to see the album, post, etc) -> Hide this from (people you don’t want to see the album, post, etc) -> Save setting”.

I hope this helps.
