here the report is in unhandled but the post is deleted.
In this case i think the status will stay forever in unhandled as nobody can handle it anymore.
(no issue for me i keep reporting just want to share this case to underline that removing after some time will make sense.
The reason for such thread to be on unhandled status is that it was trashed, but, the posts weren't deleted. If the topic has been deleted, your report(s) should be automatically marked as good.
You will have to PM a global moderator or any moderator on that section/board where your topic was reported. They will manually mark it as good.
In addition to unhandled reports, staff are
voluntarily passing it up the chain (or perhaps ultimately letting it fall into perma-unhandled) because they're uncertain [1]. So, it is not about merits or ranks that some reporters thinking that the staff handling a specific report don’t have the power to do a task, it is about the uncertain possible actions to be given to your exact report.
Thanks to [1]theymos, mprep, and Halab (PM conversations about reporting).
