Hey Dear, I don't know that it is previously posted on HN.

Also I have posted article different from platformer.news article.

Also Reuters and other news website have written posts like mine one and posted on HN.

Then why my post was flagged by HN.

It was flagged by the users, not HN. The users flagged it because you should have checked whether it had already been posted.
