Facebook haunting 

When someone Facebook murders you, you haunt them via mutual friends by talking to them or about them through mutal friends.

Facebook haunting 

The opposite of Facebook stalking.

'Facebook haunting' is where someone you hate keeps appearing on your friends pages, posts comments on their statuses, and just basically is always visible.

"That dickhead Tristan keeps Facebook haunting me!!!"
