Tagging onto the top reply, just to provide an update.
This morning, the initiating reporter in question posted an apology to his/her weibo. https://imgur.com/a/8jctyNP I will post a full translation, and you can draw your own conclusions from it.
Here's the translation:
Sorry, I am apologising for my mistakes to all affected parties. Because I am irrational and I caused huge amounts of negative impact, I am apologising to everyone.
I really did not predict that this action would spread to other areas and caused impacts, but from what has happened and the results, I am disturbed and terrified, for all who were unrelated but dragged into this, it is really, really all my fault. Please scold me...
Before that, in my friends-only post, I spoke about publicist, this refers to a friend of mine who works in the publicity industry and I inquired on this topic. I am not part of the Counter-Anti squad, and I really, really did not contact XZ Studio or have any relations with them.
I hope my mistake will also be a warning to others. You really cannot be too ignorant or reckless... and if you do wrong, there are some consequences you can't face.
Once again, I am apologising to all who have been negatively affected by my actions.
