re: It's a community
No, Matt. It's a business, as you have repeatedly shown. Whenever you are confronted with a decision, it is very clear that you do what makes sense from a business standpoint. And getting people to police your site for free is simply a great business move, if you can find any takers.
But, please don't try to shroud what you are doing in some altruistic pablum. If you find anyone who will do your police work pro bono for the "good of the community", you have found your pigeon.
Truly "A is B" logic. It's for the good of the business, folks.
