Lawyers are sticklers for meaning
I've never heard of it happening. And it's sounds really improper. But the OED says blackmail is:
The action....of demanding money from someone in return for not revealing compromising information which one has about them.
So for it to be blackmail, she would have to be demanding the money and threatening to "go public" if she didn't receive it.
But she's already gone public and doesn't want the money. So it certainly sounds coercive, and it might have been bribery, but it wasn't blackmail; it's the wrong way round.
