Of course.. according to RIAA/MPAA if the IP address shows illegal download then someone is obviously guilty and there is no reason to suppose otherwise. They paid enough money in bribes to make sure the 6 strikes law went through, so they expect returns.
"Innocent until proven guilty" is no longer the watchword, whether it's online "piracy" or terrorism. The government routinely assumes anyone accused of terrorism is a terrorist, so why shouldn't the RIAA/MPAA?
There is no law here, and no bribes were paid to the government this time. The government isn't involved here, but they should be. This is a system made by RIAA/MPAA, because they could not get a law through Congress for it.
