Yes I have found it is a bit easier to block on facebook but a little more complicated with a cell phone and then it will also depend on your model the exact procedure. When I built my first fan page I was trying many apps and methods like how to buy facebook fans you learn alot about how facebook works then of course they may change it all the following week. Yikes.

Maybe your particular customer service can assist..good luck my friend I know that can be a royal pain.
