Anyone considering legal action of any kind has to answer some questions: what is the best possible outcome? What's the worst? What are the chances of each of those outcomes? What's the result of taking no action? Is the reward for a good outcome worth the risk of the worst outcome?

So, for example, an astronaut considering any action against an HB would list things like:
Best outcome: one annoying insect gets smacked down, and I get awarded some money plus the satisfaction of proving the reality of Apollo once and for all.
Worst outcome: the case is thrown out and I'm stuck with the legal costs, plus the HB gets a lot of publicity and "there must be something to it or he wouldn't have sued" credibility. Or, I win but the HB doesn't even have enough money to cover my legal fees and court costs.
Take no action: HB gets to keep being annoying but hardly anyone pays attention.

Rate the probabilities as you will, the third option will pretty much always come out on top.
