Obviously, the purpose of the website this guy was running was pretty specific, but according to what you posted, facebook would be liable as well. If such a case ever actually got to court, it would no doubt come down to an issue of whether facebook was itself posting links to copyrighted content, or whether facebook was merely providing a forum in which others posted such things. It's the old geeks-trying-to-understand-law problem. The geek says "Well if A is illegal then B must also be illegal. And if B is illegal then C must also be illegal." And so on until you've reducito-ad-absurdumed your way to the conclusion that Z must be illegal, but nobody would ever think Z is illegal, therefore A can't be illegal. Since nobody ever gets fined for travelling 0.01 mph above the speed limit, it must be okay to drive at 120mph down Main Street. The courts don't work that way, however. They apply fuzzy tests and arbitrarily declare that A through D are illegal but E and onwards are okay.
