I recently had to block find the cause of a high bandwidth usage at a client.  I was suspecting heavy facebook games or music downloading. One of the sales guys opened a site at 8 in the morning and watched video clips all day.  It is now blocked.  I tried this site at home and found out why he couldn’t stay off.  You can;t stop clicking 😉
