Croker, on another site, someone said something about that NBC news bit, so I'm going to ask the same question I asked there - can you post the link? I believe there is more to it than simply "if you post a photo". The Terms & Conditions of each site comes into play. For example, here on Find A Grave, it is clearly stated the copyright remains with the contributor, but over on Ancestry, the T&C states by uploading you grant Ancestry license to redistribute in whatever manner they deem appropriate. Most hosting companies (like GoDaddy.com) prohibit posting anything that will violate the intellectial property rights of someone else (ergo, don't post what you did not create).
And, no, my state attorney (and I doubt any other) does not handle this type of theft because copyright is an interstate issue.
As to the "copyrighted" books... "facts" (the names and dates) ARE public domain. No one can "own" them, because no one created a fact. What is copyrighted is the 'collection' as a whole (the entire book) and the 'original presentation' of those facts (how the facts were arranged).
Duping when denied a transfer is "bad behavior". Rewarding bad behavior only encourages it.
