The Pirate Bay has already been blocked for me for the last year, maybe more. Only one ISP in Ireland (Eircom) has done it so far though, Eircom used to be the dominant ISP, they aren't anymore. I see this when I visit TPB:
I bet they lost a lot of customers when they did this, I should have switched but I don't pay for the internet
Anyway, enabling governments the ability to do this is NOT good. It also won't stop piracy at all. People should realise that any kind of censorship will just get worse, just look at SOPA and PIPA. I know this is an American thing but the EU and countries within it always tend to follow America's footsteps and introduce similar bills. If we allow the governments to pass laws like this, then even more severe bills like SOPA and PIPA will make their way over to us.
