XF 1.5 How to hide thread from other users?

Let's say there's a user ranting. You don't want to delete their thread, only to have them rant some more. Instead, is there a way to make it so that only the admins and the user see the thread and any replies to that thread? This way other users won't see it, only the thread starter and admins. Any help appreciated.
I don't want to move the threads or set permissions for the entire forum so users can only see their threads. This is a public forum where users help each other. Just want to somehow make it so that if a user is trolling, the thread can be set so it is only visible to him and the admins so they don't know that it was hidden.

To make it so only staff and them could see one particular thread would require an add-on or custom development.

There are node permissions and you can even apply permissions to a single user, but that would make it so they only see their threads in the entire forum.
