Today is a very sad day! I just found a Flickr-account that has systematically uploaded many, many of the files I have shared for personal use with my readers and followers in the past two years. She also shares them with no limitations, including many files from my Exclusive folder that I have specifically asked my followers not to share with other non-followers.
My digital files are copyrighted under international law, and as thus they are my property. Even if the original images are in public domain, I invest hours and hours of work, skills and effort into scanning ephemera, cleaning and enhancing the images, sharing them here with you for personal use, and organizing a large archive. And I have been doing it all for free, for the mere satisfaction of brightening my followers days. The digital files are automatically copyrighted, and re-sharing them is a crime, violating international laws!
I have notified the Flickr-user that has so many of my files posted, and await her response. Until then, I have locked the Exclusive folder with immediate effect.
I apologize to all the other, loyal followers! And I will happily consider your applications to join the Exclusive folder in a more secure way, but at least for the time being, this will no longer be an automatic feature including all new followers.
