By the way, Skeptic, the "nuisance lawsuits" you refer to (if they are intended to curtain speech, and not more questionable forms of "activism") are not legal, not in California, anyway. They are called SLAPP suits, and in California they are subject to summary dismissal unless the plaintiff can show at the outset they have merit. And if they are dismissed, the plaintiff can be made to pay defendant's attorney fees. That's established by statute; probably some other states have similar rules
