As outlined in another comment, marketing/seo is often the reason. That is, bots will spam links. Either they want direct clicks or at least some SEO bonus.

- eli 15y agoThe worst is the bots that are smart enough to figure out how to post spam on your site, but not smart enough to see that it's all rel=nofollow
- TomGullen 15y agoWorking out if they are nofollowed or not probably is comparable effort to just posting the spam link! Therefore just posting the spam link is probably the best strategy for them.
- Natsu 15y agoFor one link, yes, but for the entire site? I wonder. I can't imagine there are any search engines important enough to optimize for that don't use the rel=nofollow cue.
- danneu 15y agoI'm not convinced nofollow links are valueless.

- tagawa 15y agoDon't know why you're getting downvoted - you're correct. I've seen one or two SEO experiments (one on Seomoz IIRC) that show Google at least includes nofollow links in its rankings, even if it doesn't value them highly.
