BTW this is my report stats and my target is to get the 100% accuracy in future

You know that is impossible, right?

That is not impossible. That is possible.

Sorry for the late update on the report statistic

You are not late as you have updated earlier. And nowadays people not updating anymore.

will you report each post, or make a single report?

I think s/he report each post to increase quantity. Also, moderator usually does not remove all posts if there is a report for a single post.
