This took my by surprise. For those of you who don't know, most anime that floats around on the internet comes directly off the airwaves of Japan and is redistributed after being subbed. Of course those raw files are also downloaded by native speakers of the language to just watch as is. This is a problem however in Japan because the piracy has grown to an extreme level and is majority hurting sales of anime. For this reason the major ISPs have decided that if anyone is caught doing file sharing they will be banned from the internet. Obviously not permanently but if repeat offences should occur just that will happen.
I'm not to concerned since this is mostly aimed at people who use the engine Winny and anyone who has half a brain who is in the anime area would have switched to Share by now. However I don't know the details of how the programs work. So I'm still a bit scarred of the anime I so dearly love becoming inaccessible because of the radical actions the ISPs in Japan.
The most surprising part is that the government isn't involved at all this is purely a commercial action.
