I have met the person you are talking about. She has got upset about downvotes before when votes from a certain troll were cancelled out. She refused to try and understand the reasoning behind this. I get that some take downvotes more personally, but it is a core part of Hive and nobody is automatically entitled to rewards. She has done pretty well anyway. I suspect she looked at 'the other place' and Blurt, but probably won't make as much on those and so is still on Hive, despite complaining, at length, about how toxic it is.
There is still no excuse for 'doxing'. People can choose to be at least semi-anonymous on Hive even if it is not too hard to track them down. I see she edited some comments, but the blockchain does not forget.
Attacking the community is not going to do her any good. Downvotes do not have to be justified and those who are pissed off may feel like using them.
I would still not try to drive someone away from Hive unless they are actually abusing it and will not stop. It remains to be seen what her future can be here.
