Serious issues in Identifying Article vs Blog

I have been keeping track of the most of the articles and blogs posted here. It looks like whoever is reviewing has no idea to judge whether it's an article or a blog. Just an example - http://www.c-sharpcorner.com/UploadFile/41e70f/consuming-static-resources-in-Asp-Net-core-1-0/ This is a perfect example to post as a blog than article. The interesting part is, if I post an article with an average of 2 page content, it's automatically converted or treated as a blog with out even asking me that it's good to post them as a blog. There got to be a favoritism going on. That's the least I can think off.
