And time and again you have had scraper pages wind up in the search results against the search engine guidelines with various excuses each time. On those types of pages Google states "Avoid "doorway" pages created just for search engines, or other "cookie cutter" approaches such as affiliate programs with little or no original content." so no...those are not at all within the guidelines (or even the spirit of the guidelines).
Syndicating content without asking permission and providing no way to opt out and putting nofollow on the links is also a quite dirty business practice.
Keep in mind that scraper sites are not something you learned from me. If someone like me puts up a site like that it is burned almost immediately. Whereas your site has been scraping content for years. (I have never ran any scraper sites, but when Teeceo did what you are doing Matt Cutts described it as "shoot on sight" publicly on his blog)
