Violating someone's privacy may not be as serious but it could conceivably be a personal disaster.
Genealogists run more of risk of violating someone's perceived right of privacy than they do of being executed for revealing state secrets in the U.S. but that may not be so true in other countries of the world. Privacy laws are vague in theory at best and really vague in practice. Some of the concerns addressed by the so-called privacy laws include:
- The right to communicate without being overheard or monitored
- The right to behave differently when alone than in a group
- The right to be left alone by governments and other entities
Now we have state or company secrets and privacy concerns, are there any other limitations besides copyright we need to be aware of? As a matter of fact, yes. There is plagiarism or claiming someone else's work as your own. Facts cannot be copyrighted, but work product should always be attributed. If you copy someone's work, have the common cutesy to give them credit where credit is due, even if there is no copyright claim to the work. Of course, this issue grades into the bugaboo of ownership of genealogical information. No one owns facts. But if someone's research effort has produced a competent set of facts, give credit for the work and effort.
In any of these areas moderation is advised. Do the work yourself and don't be too quick to worry about people stealing your work. But stay far away from the other non-copyright concerns.
