XF 1.5 Hide Thread until replied

[998877]

I am looking for a solution to the following challenge
One of the reasons I use my forum is for learning purposes. I give people an assignment and they need to answer that before they can see what other people wrote.
I would love to be able to hide all posts and replies until a user created their own reply.
I did find: https://xenforo.com/community/resources/aayush-hide-hack-v1.1618/
But that requires to add tags in the actual post.

Any suggestions how to tackle this ?

I think I would love : https://xenforo.com/community/resources/show-first-post-only-two.4637/
But then hide for all users who have not yet posted in this specific thread.

Any suggestions?

It would require custom development.
