Here's the bad way: A vicious cycle occurs (similar to diesel engine runaway, where that it must be clogged for it to stop) where immature kids join the community at a sort of exponential rate, and the mature people become diluted. The community will then turn into a state similar to Minecraft and ROBLOX.
Gen. Hothauser's more calm way is the 2nd way.
