Let me see if I can provide some insight into your question:
Our Referral Report does provide a specific id to each referral, and allows you to see which site your referral came from, as well as all their performance stats. Personal details are not disclosed as a means to respect privacy. A profile can be set up to track individual campaigns, where you can see the performance of each profile that is set up.
Feel free to contact me if you have any other questions.
Hope this helps 
Thanks
