Re: Excuse me
...There are many images out there that, when fed into Google Image Search and the likes, will give hundreds of entries. Seeing the large quantity of results, will be an excuse to say they couldn't find that drop of water in the ocean...
Your view of the legislation is laughably incorrect!
If you are responsible for carrying out a proper due diligence search on millions of images then you have to do it. Properly. You can't just say "I thought it looked difficult, so I didn't bother". Or rather, you can say that, but the Judge will reply "You admit you didn't do it properly - Guilty".
If you do do a proper job, but still end up using someone else's work, then they don't lose the copyright. They can come after you, have it taken down, and be paid compensation from the fund that you HAD to set up when you started using orphan works.
If they try to delete the metadata and claim that it's not your work - well, they could do that anyway now. This law doesn't make it any easier, or any harder....
