Well, I just wanted to underline the fact that Google doesn't care about advertorials (even if they give air that they do), but rather paid links within an article. People here have been way too jumpy lately, thanks to google's FUD, so it seems they often group things together that they shouldn't.
For example, if I paid a guy to simply mention my website in their next article, which is not directly related to my website, but is on the same topic. Sure, it's not really an advertorial in its strictest meaning, but exactly the thing google is trying to get rid of.
As far as advertorials with no dofollow links - there are plenty of those. One example is a hype-generating article, those don't really need to have a link at all. Another all too common one is the affiliate advertorial - a website will publish an advertorial, but use affiliate links, instead of direct links and those affiliate links could be run with a redirect through a search engine blocked folder.
P.S. Speaking of advertorials and disclosures, I believe that as long as you do so on a personal website, you should be well protected under free speech.
