Posts are not automatically moderated just because someone decided to report them. It’s up to the moderators to decide what to do with the post report, so there is nothing wrong with someone reporting a post. Users are also not required to disclose whether or not they decided to report a post.
Given that the vast majority of your post reports are rejected, I would think that you would understand this better than most users.
I do not know what post reports were made in this particular case (I could look it up but it’s not my forum to moderate), but let’s not give anyone any grief over whether or not they decided to report a post.
