Your post is a perfect illustration of the fundamental problem with Google's author tag. Because somehow, as soon as you implemented it, your site apparently acquired a lot more authority and value in Google's eyes. That's nonsense, but it's also exactly why the author tag is so attravtive to spammers. And Google's past efforts to stop spaamers have mostly failed -- I doubt it will be any different this time.
