In my personal opinion we should start with the users that have been declined the new license.
Therefor I have posted a list of actual decliners in the first thread and here what is left of their work:
- Cetest
- jkjk
- ulfl
- JohnSmith
- amai
- Stefan de Konink
- moonwashed
We still have a chance that the others will agree the new license, right?
Is there a way to identify the nodes / way / relations of those users only?
P.S. User Markus B is somehow copied and not a problem anymore.
Please ask google for this user as I also don’t really understand what this means 
I just know that he is not a license problem anymore.
