Pretty sure the secondary reason was to get KV and the law twits riled up, given nicks sense of humor.You make a fair point. Ron is a nobody, so it's not like anyone would care if he left them zero stars, but Monica is enough of a public figure that someone could theoretically want to sue her for saying something negative about them. It would make sense for her to have such an insurance policy. Still, I think those policies would cover defending against frivolous suits; I doubt they would pay if the defamation claim succeeded.
And Nick doesn't have to dox himself by putting his address on the corporate registration, like certain other dumbasses have done.
(Although Nick has a P.O. box, so he could've also used that... but it makes sense for him to just put BHBC's address on there because he'd be having them handle any issues anyway.)
