So if you crack the holy grail of AI, it still means you can't even link to other sites you made.
IE Google Mail can't link to Google Trends as it is irrelevant?
Without more information how they do that, we are in a very dodgy area here.
Relevance, regarding it was made by you or your friend can't be detected by a link list.
Maybe you are just linking to a site you want other people to know about. How you gonna detect that with an algorithm? You can't.
