Their park, their rules, and if they are comfortably full with RVers then it works for them. If State regulation says no animals left unattended, and since the RVs all have license plates, making them vehicles, it would appear they are following regulations. Perhaps they were cited because another camper or a neighbor filed a complaint. If my intention was stopped there for the night I would have no problem with the rules. If I were stopping for a few days, I probably would pick another campground just in case we were to go out for dinner. JMHO
