Already blocking 15 facebook login ip address which can be added to or 
changes by FB anytime. Do not run a separate proxy on my server. Seems 
like over kill just to block a single domain name. Any other suggestions?

On the company floor we have a cell phone signal jammer, so employees 
are forced to leave building to use their cell phones which make them 
show up on security video. Since we started that last January, people 
just turn off their cell phones at work.
