Even if Google indexes these profile pages, I doubt if the backlinks from them give much of a boost to your site's rankings. Has anybody ever seen any backlinks from profile pages listed in the "Links to Your Site" section of Google's Webmaster Tools? That's a test I use to judge whether or not Google gives any value to a backlink.
