SCMP is a paper in Hong Kong, so should be credible.

Tried this little experiment, here's the reporter in red on baidu:

Tried the reporter in blue on baidu and no relevant results to her:

Jail-wise, hard to say, but her livelihood is going to suck for awhile.
E.g. organizing protests or selling banned books, but I don't think an unintentional meme starring oneself is up there as a jailable offense.
However I do see her job getting harder as a result. E.g. getting assigned to more boring stories, being denied a press pass.
I don't think China is a free country, but if you dig a little, you'll see that many people openly speak up and protest. Big labor protests that don't make it into western media are quite regular.
Do reporters get ruined for body language implying they might disapprove of what a single congressman says (but it might be a held-in sneeze too) ?
No.
Imperfect democracy IS NOT THE SAME as a dictatorship.
BTW: let's hope being ruined for life is all that happened to this woman. She wouldn't be the first one to be brutally murdered.
