Really? Your first reaction is that she must be making it up? This is hardly a far fetched scenario. I’m guessing she didn’t bother posting screenshots because most people wouldn’t automatically assume she is lying.
She is making a case in the court of public opinion.
Granted she has more clout than the “average joe” (and the very fact that this is even being discussed is evidence for it) but ANY case without corroborating evidence is just hearsay.
She should “put up or shut-up” and the levels of “put” required are so minimal that her PR credibility before the “court” on this matter has a very short half-life.
An anonymous poster on reddit had a similar issue a few days ago [0]. Their comment got 331 points on HN while this one got 257 points so far. The anonymous one got more points.
Is it possible you're wrong about this aspect?
