nofollow was meant for affiliate (sponsored) links...
OK, see, now you're just poking at me :).
Nofollow was meant for spam purposes, not affiliate links. That was for webmaster's benefit.
Using nofollow for affiliate links was a perversion introduced by Google and is for Google's benefit not the webmaster. It's a stick you're being controlled with.
