Why bitmedia hate me and rejected my website as publisher? Please let me know how can I do better so I can make some changes maybe.

No hard feelings mate, we don't hate you or your website for sure ^^
I have no info about the particular website, you can write to support since they reviewed your site and had their reasons for rejection, and ask them for a piece of advice for improvement. As on me again, first thing you have to check Similar\Alexa for at least be presented in the list, preferably having >100k rank of course. Keep rocking pal!
Alexa ranking just below 1 mil. Still working hard to gain more traffic now as my website are relatively new.
