Thanks for detecting and removing the worst of the remaining issue. I've added the close paraphrasing tag in the hopes of encouraging review and cleanup. A search of the article's history shows that content entered in May 2010. For example, see this addition, which is not only taken from but clearly cites the source. Problematic content was added in this sequence of edits, which also includes content from other sources. I don't know if those include pasting or close paraphrasing as well.
