Shock ... I have no doubt that it does happen and in leagues where winning JV games is a "big deal", I would agree that the AD's probably should address as nothing positive is going to result from this kind of behavior/sportsmanship. With that being said, I would hope that we could get to the point where coaches and parents understand that winning JV games should not be a big deal.
By the way, our school has gone down to Kentucky the last two spring breaks to play some good programs down there, and JV is done much differently. Most schools carry about 15-18 girls on their softball teams (and this can go all the way down to 7th graders). When the schools play each other, they first play the varsity game immediately followed by a 5 inning JV game. On that roster of say 16 girls, they might have 5 girls that play varsity only, 5 girls that play JV only, and the other 6 girls play in both games. So the catcher from the first game might be the pitcher for the JV game. We've played 5 different schools down there the last couple of years, and they all did it the same way, and 3 of the teams were ranked in the top 20 in Kentucky at the time we played them.
One other thing ... these are Division 1 and 2 size schools, and they play a high quality of softball. My understanding is that they don't have the 27/23 rule. They also don't have 4 different divisions like Ohio does ... there is only one division and only one state champ crowned at the end of the year.
The point is that our girls in Ohio are fortunate that most schools have separate JV teams for the most part, and that quite a few schools have either freshmen or JV B teams. If we went the way of Kentucky, I guess the issue of people complaining about varsity players being called down to stack JV teams would become a moot point! And coaches would only have to deal with 15 sets of parents instead of 30-50, and gym time in March for only one team vs. three! As for me, I am just glad that we give more girls a chance to play ball.
