(This question is not about
nofollow, which is something different.)
I've noticed that all external links are marked with the
noreferrer attribute. The only discussions I can find of this on meta.SO and meta.SE are:
- Archive.org URLs without asterisks not handled properly in comments, where it was suggested as a workaround for a bug on archive.org.
However, I don't see any explicit statement that either of these were the actual reason for adding the attribute. Or was there another reason?
Removing referrer information does have a downside. By preventing website owners from discovering what questions they are linked from, we lose the opportunity of them visiting the question and contributing their expertise.
