Revisiting http://mail.wikipedia.org/pipermail/wikien-l/2005-May/023760.html and checking the long long long list of images at [[Category:Images used with permission]] there are many of them kept becuase they were uploaded before such date.
It's been more than a year since the ruling, I believe older images weren't removed in order to let uploaders tag them properly, find replacements, or so they could be processed at the old Vfd.
Quoting Jimbo
"It is very unfortunate that such images are still being uploaded _new_ when we have not be happy about them for a long time. It is not fair to contributors who are working on such things, since we have no intention to keep them in the long run."
Well, if in the long run they have to go, it could start now. So, I was wondering why aren't they being processed yet. I'm thinking of nominating batches of them at IFD every certain time. On the other hand, however [[WP:IFD]] is clogged, so I was a bit hesitant about doing so without more feedback.
Thus I created [[User:Drini/OldCopyrightedImgs]] which has a small sample for the first bacth and shows how I would be nominating them. I tried to sample different kind of images (uploaded by the webmaster's site, by random users, by respected old users, without source, orphaned images, etc) so we can get an idea what we're dealign with.
Still, IFD is overloaded, so maybe better alternatives can come up? Maybe a IFD-like for this kind of images?
Jimbo, what's your current view about such things?
