Who cares? Why is this a big deal? I am so unbelievably unimpressed with the seriousness of this, I feel like there is such an enormous effort to pretend this is "serious business" and "the integrity of reddit" (?) is somehow being compromised. We all knew this could be done. On any forum. Reddit is a silly place. Reddit is a place for people to shitpost memes and puns with throwaway accounts. The Donald is a subreddit that revels in trolling and messing with people, spewing toxic garbage nonstop. They riled up the main admin of reddit so much he did something childish -- a pretty impressive trolling effort. That's the end of this story as far as I can tell.
Just think, the admins have the power to edit your comment as they see fit and you'll have no proof as your comment isn't even marked as edited.
It's a scary thought.
