Do Facebook apps post onto your wall things that your friends can see but you cannot?

[Emily]

I was on Pinterest (I had logged out of Facebook, but cookies were still enabled). I don't particularly want my activity showing up on my Facebook wall. Will apps such as Pinterest post onto my wall for my friends to see but keep it invisible to me? If so, is there any way to recover the hidden posts and delete them?

Emily,

There's a setting in Pinterest to auto-post on your wall. You can turn it off. As far as deleting the post shown on FB, you can hide it from your timeline. Hope this helps!
