Speaking from just a purely technical point of view, doesn't facebook track so much of your data that its smart enough to find out who the owner of a facebook profile with fake name and does piracy and who he is in actual life,where does he live, what places he is at?
Probably. Buy I think Holywood backed down a little bit on the whole "pirates are killing us". As research flows in less and less people believe them.
I suspect the behavior will continue for a little while unhindered until one of the big studios sues. See: Viacom v. YouTube.
The studios can at the very least harass Facebook until it does something.
