working through the blocks they put up in a lab is like figuring out the 5 degrees of separation.
everything is connected to everything if you know how to find the links, so you just go from one to the other.
for instance, a school computer will let you access college sports, so you go there to college wrestling, which links you to pro wrestling, which links you to event promoters, which links you to Vegas, which links you to porn.
so i've been told (i actually saw a guy do this)
