Trying to find ways to get worlds to fill is good, but as noted above this creates more issues than it solves. New owner decides HBD looks like fun, plunks down his money, finds a world/team and signs up. A week later, he's tired of reading through the useful forum posts one more time and really wants to play a game. Or set a budget. Or hire a coach. But he can't leave. Support says sorry, those are the rules. If the new owner is me, my next step is to call my credit card company to dispute the charge based on not getting what I paid for. What do you think the odds are that I ever try again?
Someone new to HBD isn't going to know to check out the world chat, look for absurd win-loss extremes, franchise hoppers, collusion problems, etc., before signing up. We want people who try out HBD to have the best experience they can, and if that means changing their mind about a world, good for them. Better they end up in a world they like. If you lose an owner who does not want to be in the world, you have lost nothing.
A basic truth remains: Good worlds fill.
