Now that most of us have Timeline, we need to learn how to use the “feature”. Many don’t like junk on their walls and Mafia Wars requires we add a lot of it. In order for your Mafia Wars posts to appear on your Timeline, you need to go to your Activity Log and add the Mafia Wars Application. For instructions on how to do that, go here. To get your posts to appear on your wall, you must write something on the post. A very common question we get on the fan page is how to remove posts from your wall. I usually remove my Property Part requests once they expire.
If you hover your mouse in the upper right corner, you will get the option to “Edit or Remove”.
This is somewhat deceiving because there is no option to delete the post. You can only “Hide from Timeline”. This is good enough for me but those with OCD want these posts removed.
To totally remove a post and not just hide it, click on the time stamp link of the post.
You will now see a drop down arrow in the upper right corner.
When you click open the drop down arrow, you will get a delete option.
Click on “Delete” and a confirmation screen will appear. Just click the “Delete” button and the post will be removed. Don’t check the “Delete all app activity” box or your Mafia Wars posts will stop appearing on your Timeline.
When it comes to computers, there is always more than one way to skin a cat. As mentioned in the comments, you can go to your Activity Log and delete posts from there. This method is faster if you want to remove more than one post. From your Facebook Profile Page, click on "Activity Log".
Then open the drop down arrow in the upper right corner and click on "Mafia Wars" (or whatever else you want to remove).
All your Mafia Wars posts will be listed. Click on the little circle located to the far right of each post and a delete option will appear. You will get the same confirmation screen as shown above.
