I learned of this woman's situation from the coverage of ADV Podcasts on YT. They talk about it as though it may have had something to do with a play for leadership of the CCP, and that there is no way could her social media post have cleared the censure protocols unless it had been originated from or blessed by the CCP. That actually makes her situation worse, as it means she is possibly a pawn in a political hit job. Not that it means that the post was false, only that it was being used indifferently to her welfare.
I find it disturbing that the fake "I'm OK" statement was written and ostensibly coerced is that it was not made by video. If she was in any condition to appear unharmed, the state propaganda folks at the CCP would have included something like a selfie or a video. Sent to the gulag anonymously is probably the most likely answer. Would she be recognizable to the people there? No way. Just like the average American "tennis fan" could walk past any WTA player on the street, except maybe Serena, and not recognize them.
Not sure what can be done. A call from Uncle Joe to Mr. Jinping seems unlikely.
