3) In the USA I am not aware of ANY websites that are blocked by a court or government order. Even the RIAA and MPAA have not been able to accomplish that one. I'm sorry that the UK and other European governments have decided to implement thought police, but as an American there's not really anything I can do about it.
Sorry I had to be the one to ruin that rose-colored worldview of yours, but we (the USA) don't even screw around with the blocking part; we seize the domain and pretend the site never existed. It's kind of a big deal.
I'm saying that placing some anger on an entire country trying to hack our citizens seems like a good outlet for their 'creative energy'.
Anonymous doesn't have citizens.
