Challenging to unravel the why, but Public Domain Review shares a tragic loss of public domain content from Flickr
It seems to be some issue of what is determined as a “photograph” in the Flickr Commons as well as what happens if they are posted from an infrequent account. The discussion in flickr forums goes long, though down at the end there is a hint of a possibility of reversing this act.
There is a call to sign an open letter asking to undo this act
I would appreciate maybe some more insight into this situation, thoughts, examples or experiences in using this collection or thoughts on what happens when a part of the commons is slashed. What can we do as members of the commons?
