unless it is filed with the Copyright Office, and *only* if it was stolen *after* the date of registration.
This is totally unnecessary. Copyright does NOT have to be registered. It is protected from the day it was created but you may need to prove that you did create it and when. Registering it with any authority or notary is one way but it's not the only method. For example if the Wayback Machine features your web site and it has a record of the web page in question you should be covered. Or if every now and then you published your web site to PDF and sent a copy to your solicitor or other notary you will be covered.
The same applies to all media... images, video, articles, poetry, etc.
