Google’s Gary Illyes said this morning on Twitter that it makes sense to use the nofollow link attribute when you link to bad sites.

Sometimes when I cover stories here, I have to link to examples of really bad sites. Often, if the site is really bad, I will use the nofollow on those links.

So when linking out to bad sites, and your gut makes you feel bad about it, use the nofollow, it can help with indigestion.
