Re: Unpublicized website gets hammered by spam?
Well... if it is on the web it is publicly available — regardless if you've publicized it or not.

If you're concerned about false registrations while your site is in development, you can simply "close" the site until you're ready by uysing the Close site... option (also on the Admin: General page, Navigation tab.
