Feels like you somewhat missed the point of it all?
The new "junk" section isn't supposed to be used to bring further discussion in that specific thread. (EDIT: Similar to a -closed-, but not removed.)
But to prevent people from posting new of the same threads while their previous got removed, and not having threads where the only question is "why did my topic get removed?".
Off-topic should be used, but this section would be of a whole other purpose.
