Morten:
Thank you for sharing your observations and concerns. That is most unfortunate. There is some things that you can do to protect the uniqueness of your collection and that is with editing or adding a "Watermark" to the photo. Changing the color can also be a choice, I thought that was what you had did with the photo of the "Hindenburg" sailor?
People who share their work with the world, will likely face the issue that it is borrowed or stolen. Frankly, In my humble opinion, this brings up the interest in your physical collection more to a broader audience. I have noticed that you have been signing with your full name instead of your moniker.... Would you mind sharing your reasons for doing this recently?
This forum is very nice, I too appreciate the members here who are very civil, helpful and pleasant. That is very important to me, as I am sure for many collectors and purveyors of Militaria. This might be worth seeing a post on this forum which specifically addresses your concerns with the administration?
Best Regards,
