You know, you make a wall to pay tribute to someone and there’ll be some idiot who’ll ruin everything by putting a sticky that says “you suck”.
Now, you can keep these idiots out by turning on what we call the Idiot Filter.
If you turn the Idiot Filter on .. all posts on the wall would require you, the wall owner, to approve them before they show up on the wall. To turn the filter on, just click this option on the Wall Builder:

If you want to turn the Idiot Filter on on an existing wall, just log in to your account and edit the wall. Any future posts on the wall will require your approval.
So, no more idiots!
