I might have found a Facebook hack that might be useful for viewing
blocked profiles that are private.
Lets suppose you're in a Facebook college network and the profile you want to
view is from the same college as you but they've blocked you.
You can't obviously make another Facebook account because you still
can't see their profile because they belong to the college network...
But if the profile you want to view is also in another non-college
network (country, city, etc) then you can view their profile EASILY by
creating another Facebook account and joining that city/country/etc and
then searching for them and voila! you can see their profile.
