This isn't analogous to collecting donations for a charity and then making a bulk donation. It's analagous to collecting donations for a charity, taking a cut of those donations for your troubles, and then depositing those donations in your bank account until the charity you supposedly collected for comes and asks for them.
If creators don't register after a decently long interval, the tokens flow back to the user growth pool. Users may choose to support only verified creators/publishers. As we scale up this user growth pool "powerball" effect goes away, and the BAT becomes more dear vs. fiat, so the pool lasts longer as grants and matching scale down in token quantity per user.
and then not depositing those donations in your bank account until the charity you supposedly collected for comes and asks for them.
Probably a typo :)
