Not that it's worthwhile to drag this out, but I rather presumed the term referred to the person's normal role in the real world. A public relations professional is a kind of paid advocate, but whether they advocate here is a separate issue. Though in some countries there is a different marketing culture where public relations professionals are seen as consensus-builders between companies and their respective publics, rather than advocates. I prefer to just use normal business language like "marketing" rather than Wikipedia jargon. But if you insist on labeling me as a "paid editor" I think I will start referring to others as "free editors" since working for free is actually the more unusual between the two (*snicker).  (Talk)
