Group permissions to view profile fields?

[Interferon]

We have a lot of spam accounts that are registered on our site and fill in the "About Me" section of their profiles with spam links. I currently have this section completely disabled to prevent it from hurting our site ranking. Is there a way to prevent the guest group from viewing member profile fields, so search engines don't pick up the spam links?
