Worlds change and evolve over the course of time. The private rules that worlds create must be able to keep up with that change, as well as with changes in the HBD community. Moneyball also had a "no trade veto" rule which meant that the league could only take on veteran owners that wouldn't do anything stupid. That rule could have been amended in many ways to accommodate owners with less experience. There was also a rule that teams could not change cities, in order to "maintain continuity". But, as jsturgis pointed out, even with 200+ HBD openings at the time and worlds offering gift cards for joining, some folks were unwilling to make any changes to rules or standards.
Moneyball owners felt this was an elite world (though they still let me in) and that they need not rethink rules or lower standards like many other worlds. Now a formerly "elite world" is on its way to becoming a circus freak show. A cautionary tale, for sure.
