Crazy thought for Worthy Core: the kids who keep trying to get in, why not make a "safe dungeon" for them and other youths, age gated, that is pure puzzle based and always has a port out option? They get their experience, Worthy gets a bit of value maybe, and Sincere can surely protect the core from some kids...
While possible, not going to happen because I want children to be as far away from the plot of WC as possible. The orphans team is basically there to serve as emphasis that kids are not getting in.
