I have competitor that scrapes himself with odd results.
From the footer of his every page on multiple sites he links to his "business" site which is a single page in size. That page republishes the latest 5 posts from his every site. It's pagerank 6, apparently trusted, and draws a good deal of traffic to his "business" site which he sells netwroks advertising from.
It's apparently all about trust now. If you have enough of it you have been granted some room to abuse it it seems.
