Playing devil's advocate: Was there something that ensured only American citizens (or residents or some relevant filter) could submit comments? I suspect there was a fair bit of trolling as well (not excusing the lie that they were hacked though).
Instead, they concocted an obviously false and politically motivated story about being "hacked".
Ironically, the democrats (or at least the current people in power and the media) tend to be against any requirement of strong ID when it comes to interacting with the government...
