Yup. I'm in Des Moines.
To keep robots from indexing profiles, log into your CP, and goto Master Settings -> Feature Permissions.
In there, you will find a checkbox called Restrict Profile Viewing to Registered Members
While you are at it, you will probably want to restrict your Member Directory also.
To do that, you will goto Display Options -> General, Community Directory Tab. Set the Enable Community Directory to Yes, for registered users.
That should keep bots from indexing profiles.
