So I got this tool yesterday. I threw in about 300 links on drip feed, which included social profiles, profile backlinks, and video syndication links.
The profile backlinks were first in the list. About 75 of them. These are links from profiles/user accounts on sites like ask.fm, foursquare.com, buzzfeed.com, etc. Previously 0 were indexed. Now about 22 of them are actually indexed (and it hasn't gotten to all 75 yet).
So far, so good. Too early to give a full recommendation / approval, but it seems promising.
