On Facebook, is there any way to block ppl on your friends list from viewing your wall?

You can create groups on facebook for your friends. I have my friends in different groups such as "family" "close friends" "work friends" "barely know" etc then when I post on the lock button I decide which groups are going to be able to see those individual posts. In privacy settings you can set it as default that whole groups or individuals are not able to see your wall either. I have it so my family and close friends can all see my physical street address and phone number for example but the rest can't. I also have it set so "barely know" only see the things I post on my wall for "everyone". Lot's of different settings in there you can adjust for your privacy.

To edit who sees your wall by default go to privacy settings > customize settings and change the settings there. If you choose customize in the dropdown list you can select individuals or groups you want to exclude from seeing those particular features.

To create friends groups from the main page go to friends > edit friends > create a list . Then on each friend you can assign them to an individual list or multiple lists. Also when you use chat you can also use the slider in the chat box to appear offline to certain groups of friends etc also. It's very useful I can't believe everyone doesn't use it.

There isn't neccasseraly a way to block them from your wall, but you can block them from certain posts. When your typing something in as a post, before you share it, click the little lock. You can click on customize and go from there

Go onto the friend. Go to near the bottom of the page and click report/block this person. OR when u set a status... before you click share there is a little lock next to 'share' click it and go to customise and select the friend x
