If you look at blogger which is Google controlled, all blogroll links don't have a nofollow. This tells me, this is a spot Google intends for you not to place advertisement links, but sites to good sites related to yours.
If you are selling links in your blogroll area, you may get caught, but my point is the intent of the section. It does sucks that people abuse parts of a site buying links.
