There could be a number of reasons why your site was banned/de-indexed or penalised, it could have been the downtime, or sites you were linking to were penalised and your site subsequently got caught in the witch hunt
They will ban you if you dont follow their guides.. maybe you do illegal procedures to make increase your website's search rank
Obviously , there are too many spam on your website, i means there are too many backlinks in the articles that published on your website, Google Panda have punished many “Content Farmâ€.
reconstruct your site and make sure you do not span . and put plugins that stop people from hacking your sites.

It seems that you miss something about your web! you may check that carefully and try to walk in Google's way!
you are running a big article submission site with tons of duplicate content. You should not allow others to post a duplicate articles in your site. I've researched some of your articles, they are copied or already published on other websites. See - http://www.google.co.in/search?sour...+then+you+will+see+that+how+you+can+make+it+… the article you've posted is already present on other 5 sites. Just few days ago google banned millions of co.cc sites just because of large number of sites over their are of low quality and also the latest panda update strikes to scrapers (copy-paste from other sites). The same thing appiled to you. You have large number of duplicate content. Now you need to remove all the duplicate content and set a reconsideration request. Google will do anything to provide good experience to their users (Googlers) Like me
