There is another group called "Adoption Angels" who have been successful in helping people like your friend using atDNA results.
I have a 4th-cousin DNA match who is an adoptee with no information about either parent. I sent her a list of my hundred closest matches and asked her to check to see if she had any of the same ones. She did not get back to me but it seemed to me that this might be one way to help her find possible relatives.
