Script for Facebook mass downloading

Someone gave me this script. Is it legal?

----

#!/bin/sh
#
#requires /usr/bin/GET from libwww-perl

d='";"' #delimiter

for (( i=1; i<=10000000; i++ ))
do
     query=$(GET graph.facebook.com/$i?fields=id,first_name,last_name,gender,locale)
     script="q=$query;if(!!q.last_name)print(q.id+$d+q.first_name+$d+q.last_name+$d+q.gender+$d+q.locale);"
     echo $script | js -
done

Don't get caught pulling a weev.

Let's see, violating the privacy of the users of a website notorious for its disregard for its users' privacy.
