Yup, what they advocate doing is patantly illegal. Furthermore note that the .de top level domain that thier website is hosted on indicates Germany. I'm not sure they can call it "civil disobediance" when they've got foreign nationals attempting to interfere with a U.S. election. I think that's called terrorism. Note also the lame attempt of these guys trying to cover thier own arse by the disclaimer at the end.
Typical leftie stuff, the only freedom of expression they support is thier own. If anyone else tries to express thier beliefs they'll use any means at thier disposal to muzzle them.
