I tried. I texted the assigner of our region's volleyball referees and never got a response. Guess they're not as desperate for officials as baseball.
As far as baseball goes, I'm blessed enough to live in a corner of the country where the worst fans (as judged by my peers in our association) are vocal, but not mean or nasty as I've heard in some areas of the country. Thankfully a lot of our high school ADs take their presence at games seriously. My son's AD had a meeting with the parents last year--yes, he knows I'm an umpire--and told the parents that if he heard any of the parents say anything negative about a call he would have a chat with the parent and consider removing the parent from the game. It was refreshing to hear, frankly.
