Does search engine robots follow the external links in your SMF forum?

Does search engine robots follow the external links:

• in the signatures of your members
  
• in the profile columns beside the posts e.g. ICQ, yahoo and MSN IDs
• other external links inside your forum

I would assume so, unless they have been rigged to have the nofollow stuff added to them. On all counts.
