My school filter blocks everything.
I was once trying to look something up about Harry Potter and all the sites were blocked becuase they were apparently about "pot"
yeah they come in real handy at times, plus I work with a bunch of software engineers But it's the main web hub in SLC all our work email filters in/out from that drives us insane! We call those guys web nazis.....they block and freeze all kinds of stuff.
Thank the LORD they haven't blocked the Blue Crack yet!
