I really enjoyed playing on Diggit.io earlier and am surprised that the admin has not posted to this thread since 1 March. The site was really innovative.
Regarding the community, any site with rain or a faucet will attract very marginal users and you need mods to keep things from going nuts and an active admin to reassure everyone. I hope CF comes back and the site recovers.
I completely agree, hiring mods to take care of basic things is something that needs to be highly considered by the owner if he wants his business and website to thrive and grow. This is essential for people to be able to trust it, especially if their money is invested into it.
