Doubt any more than 1% (or hell, no one) on Era was apart of the direct threats she received, but I guess it is possible the spreading of the story could have worsen the outcome for her immediately. But eventually the spreading also "vindicated" her, so it is a double-edged sword.
How was the backlash towards the people who did the "prank"?
It's such a very tough situation. You see a story that seems like it is exactly how it seem, and our instincts are to be repulsed by the person because the scene happens all too often. But maybe we as a society should stop the social-trials? It used to happen only in the community, but now anything can be global.
Ultimately everything has an opposite and equal reaction. I feel the amount of crap that non-white people have had to put up with has led to a feeling of empowerment that they used to not have, so the amount of hate they have seen in the past is now being repaid with this ability.
I feel like the article is just trying to caution people before "jumping aboard the mob train", but again I go back to my original thought about how no one here probably was sending threats to her. It's all just about the way/ease information can be spread now. The CNN article does an okay job showing a problem, but doesn't really go too far into it, to be honest.
Edit: And then you have the people who have "glee" that someone was vindicated, and immediately frame the whole story (and others like it) just false.... which is just another example of confirmation bias.
