You are obviously trying to promote your own company blog as well as promote your company products. In blunt words, you are spamming.

More importantly, you have a history of spamming:

https://news.ycombinator.com/submitted?id=nirajr

And from the looks of the above, you've tried using URL shortening services (goo.gl) to resubmit the same spam multiple times.

As a result of your spamming behavior, your domain, grexit.com, has most likely been black listed, and hence, your submissions are now automatically marked as [dead]. It may have taken the system over two years to figure out your spamming pattern (the system is always evolving and improving), or maybe there was human intervention involved (a moderator noticed your spam), but either way, you're now (permanently?) stuffed when it comes to doing self-promotion (spam) on HN.

Minor and rare occurrences of self-promotion (spam) from active contributors are often forgiven, but self-promotion spam is the only thing you've ever done here.
