Dupliicated results in site: command and some ideas

Well, first idea is - that the duplicate pages - do they show up in google for search terms or not?

2nd thing - do they get pagerank and links as to normal pages?

if they do then they are good for pumping it left and right

 

First, they might display without indented.
After some times display in indented results
Finally, site will be removed from Google indexes.

 

if unique content is added to these pages, do they stand chance to be added back into the index?
