I don't want to be rude - but why would you think your site is worth to be taken back in the index.
Most of your backlinks can be classified as "forum spam links" - it's nice as long as it works, but only having these type of links is waiting for spam penalties to happen.
I checked some of the content on your homepage - none of these articles seem to be original pieces of content. They seem to be copied from different sites across the web. Examples:
http://www.financialprospect.com/world/zika-virus-dangerous-than-imagination-us-25970.html - identical article here: http://www.livemags.com/2016/04/12/zika-virus-scarier-than-thought-says-us/
http://www.financialprospect.com/india-news/pm-modi-hosts-prince-william-and-kate-for-lunch-25774.html - identical article here: http://www.ndtv.com/india-news/pm-modi-hosts-prince-william-and-kate-for-lunch-1394631
So - no original content - bad link profile = added value for searchers & to be in the Google index?
