It doesn't have to pass in court as long as you have more money than your opponent. You just keep going until they run out of money.

Yes. Long ago I asked my first business lawyer something like, "Could we be sued for that?" His answer was something like: "Sure. You can be sued for almost anything. They probably can't win in the long run, but that isn't the important question. It's whether you are willing to pay to fight it to the end."

It seems to me that the anti-SLAPP laws apply in spirit here (of restricting overbearing litigation.)
