Anyway, new method(

Anyway, Facebook introduced a new list called restricted list where you can add your friend into this list and they can only see posts that you made public(setting).
Howto: Add friends into restricted lists and block them without them knowing:
1. Click the
Account at the upper right hand side of your page.
2. Click
Privacy Settings.
3. Click
Manage Blocking at the bottom of the page.
4. Click the
Edit list beside the "When you add friends to your Restricted list............you add them to your Restricted list.".
5. Click the
On this list at the upper left hand side of the box appeared.
6. Find your friend by typing his/her Facebook username at the search box and click his/her picture when the search has ended.
7. Click
Done.
8. Really Done.
p/s: I tried it myself and this howto is self written

*at step 5, when i click on this list at top left corner
i type my friend name, it say no result
when change to friend, then only show my friend
so i tick my friend and choose done, then i go my profile > view as > type my friend name
still able to see anything
any solution ??
