PDF files vastly preferred to their HTML page counterparts
PDF's are popping up everywhere as if it is the new trust factor. If I'm noticing that you can bet the spammers have.
Plus it doesn't seem like duplicate content from these article sites is being penalized anymore. Mashup article sites are literally swarming my areas particularly on the longtail. It's becoming the defacto business model.
