I was going to post here
But GCHQ already know what I was about to type.
Civil rights NGO Human Rights Watch (HRW) has launched a legal challenge to find out if its information was shared between the US National Security Agency (NSA) and the UK's Government Communications Headquarters (GCHQ). The organisation is unhappy that a ruling by the Investigatory Powers Tribunal (IPT) in February did not …
However the IPT has rejected the possibility of a class-action-type lawsuit and says that anyone concerned that they may have been spied on must submit their complaint individually.
So the IPT would be happy to receive, process and reply to an individual complaint from everybody? Seems like they're setting themselves up for a paper DDOS.
"Who’s better at spying, GCHQ or the NSA?"
That's easy to find out - although the winner is clearly the one with the lowest score in this case.
