If the person is harassing you, you can choose to report them. I think you are then asked if you want to block the person. If not, you can do it yourself by going into Edit on your Friends List. Just click the X on the same line as the person you intend to block.
go to their profile and where it should say add this person, should say something like block this user
No
No, if you block someone on Facebook, they can not see any of your activities
To remove someone from your Facebook you unfriend them and if that doesn't work you can block them. That will take them off.
You can stop someone by sending message only by blocking that person from your Facebook. Messages will only be stopped when you block the person who is stalking.
If someone blocks or unfriends it works both ways. If someone blocks you they should no longer appear on your fb 'home'
No.
search their name with a different facebook account.
Very carefully block the application on your FaceBook account.
Ok this is really simple just unfriend them or block them.
When someone has blocked you from their Facebook, you won't be able to know if they have also deleted you.
No, but there should be.
