Is there a add-on/mod that hides posts until allowed by Admin

[pk698]

I was wondering if there is a add-on or mod that allows me (admin) to hide posts/replies until I check a box. It would only hide the REPLIES, not the original post.

Maybe have a check box or toggle (show replies/hide replies).

My reason is, I want to post a contest and allow users to reply, but I'd like to hide their replies so they can't copy other people's data in the replies.
