Thanks, privacy and simplicity are very good arguments against 
collecting referers which I fabulated to be useful for establishing 
(back-)links to external pages that cite the currently viewed page.

Getting the impression "backlink" got interpreted differently in other 
comments of this thread, a quote from 
https://en.wikipedia.org/wiki/Backlink#Wikis:
