I think you got caught by the algo.
It is not natural to get 10 social bookmarks per article per day when you had (on average) only 70 clicks to your site from SERPs. Basically, it would appear that the site gets more bookmarks than visitors per day.
Secondly, your pattern of social bookmarking is very even (10 bookmarks per article per day). This pattern would never happen naturally and it is easy to spot and get caught by algo. Also, having all links from only one type of source (social bookmarks only, with no reinforcement on being talked on blogs, forums, other websites, etc) does not help.
Adding to this the content creation strategy (which results in duplicate content with 5-10 other sites for each article), and with (from what I understood) no significant amount of unique content written by yourself in a mix, then I am not surprised that your website lost the traffic.
I would suggest that you need to re-think your website purpose and business strategy.
