I really recommend contacting support (https://support.playhive.com/). Explain your issue and explain why you need it, like needing to flag duplicate posts.
However, something like this has been done before. Gyrraa, a former helper, has done the exact same thing however it’s more appreciated and voted than the original post. Even though it’s a popular topic, I don’t see anyone saying that it should still being taken down because it’s a dupe, especially from you.
And like I’ve said before, please report this to the moderators as they should choose to close this post.
