GFY's hosting company, registrar etc then have 5 days to contact GFY and have that content removed from GFY. If that content is not removed within those 5 days, GFY's hosting company, registrar etc become liable if they do not cease to do business with GFY until the content is removed.

Under SOPA, kids singing popular songs and posting the video on youtube would be no longer possible.
Under SOPA, you could harass your competitor by emailing CCBILL and saying they are billing for someone who uses some of your content (even if it's not true). Of course If it is not true, you could later be held accountable for that, but in the mean time your competitor will be out of billing, hosting, income etc for months or years.
Under SOPA, a politician could harass news site if they expose secrets that he deems damaging to his reputation.
Under SOPA, GFY would be in trouble for all the pictures GFY users regularly post.

Using SOPA to fight piracy is like carpet bombing an entire city because 1 kid is downloading an mp3. It's insane.
