Weird Indexing Issue

I have 20+ websites all of which were indexed by Google in about 2 days. I usually would just enter the URL into backlinks.itamer.com which basically submits your site to a bunch of those stats websites. Every single one of my other websites would get indexed about a day after doing that. This time it didn't work. So I used Scrabebox and SEO Link Robots indexer tools, which does the same thing as the site mentioned but just has more of them. I waited a few more days and still no indexing. Then I did a tiny senuke blast basically just social bookmarks, I manually submitted the site to Stumble and Digg but still no indexing. Its been almost 2 weeks now!

I have submitted my sitemap to webmaster tools, ive done crawl checks which all come up ok, my robots.txt is fine. Ive submitted the site to a pro Linkilicious account several times and it says it was crawled. This website is all unique content. I do have some amazon affiliate stuff on one of the pages, not the main page, but its all surrounded by unique content. Ive even added an extra paragraph at the top containing high volume search words like "Lady Gaga" and "Bin Laden Photos" just to see if that will spark Googles interest, but still its not being indexed. Can anybody tell me what the hell is going on and any ideas as to how to get this damn page indexed!
