I sneak an occasional peak on the TFP from work but it's rare. We have way too many people spending way too much time snooping on productivity including what i-net sites you visit. So... I TFP mainly from the homestead. From my primary client's location tfp is definitely a banned / blocked site. I've not gone anywhere from their network but cnn.com and the like. Their blocking softare throws up a monkey shaking his head saying that "your ip & mac address have been recorded as attempting to access a site that is inappropriate for business use". In other words... don't keep trying this or you'll be fired. In fact you may already be fired but we're too lazy to really determine who you are so this web site blocker page we hope is enough to scrare the shit out of you.
It works at least in my case.
