Someone who frequently visits your Facebook profile and looks at your wall.
Dude, you can't post that on my wall, my mom is a wall monitor!

A Wall Monitor is a subspecies of the Facebook stalker:

1. Someone who checks the status of people's relationships by seeing if they are posting on each other's Facebook walls.

2. Someone who sees a post on someone's Facebook wall and traces the conversation from wall to wall in reverse.
Wall Monitors know more about you than you do about them. They prune information from their profiles and scour yours. This is not an equal transaction.

In the future, everyone will be anonymous for 15 minutes.
