Blog deleted - no intimation

Question

Hi,

 

I'm a new member at c-sharpcorner. I posted a new blog yesterday and it was showing  under my account till yesterday. Link is

http://www.c-sharpcorner.com/blogs/specflow-with-nunit3-parallel-test-cases

 

Today when I logged in, the blog is not present in my account, also the URL throws not found. I checked my email, there is no intimation about reason for blog not getting accepted.

 

Am I missing something here? How do I know if my blog will be approved, and if not how can I improve it so that it's approved?
