I've been using the Facebook app on my iPod touch 2nd gen (OS 3.1.3) for a while, and I was wondering if anyone found a way to block their friend's updates on their exploits in Farmville, Cafe World, etc. from choking the life out of the News Feed. It looks like there's a way to do this on the site, at least for people who are spamming their friends, but is there any way for me to block it on my end? I have looked in Settings->Facebook but can only adjust options for Shake to Reload, Vibrate for chat, Push notifications.
