I was and am aware that it's on behalf of foreign enemies. Once you start putting information out on untouchable foreign servers, it doesn't take a great leap to decide that's in fact who you're assisting. And it's not like you'd be exposing information that's in the interests of citizens, you're simply playing tit for tat by gathering intel on employees. You'd easily be considered a spy, and citizenship protects you from that no more than it does from a common crime charge.
You would be screwed so fast, and I'm not sure anyone would support your cause. It really seems like a harebrained scheme to me, on par with demanding to take your weapons into NSA buildings. If you do find anyone crazy enough to do this with you, I suggest at least having a long hard think about it and doing a lot of research on every aspect, rather than jumping in head first while waving the flag around.
