I would like to try and answer this in a more generic sense than just the two world wars but by incorporating the specific World War 2 example.
I will do so by describing my thought process whenever I see a question that either mentions someone who may have been born less than 100 years ago by name, or looks like that may shortly be the case.
At the moment, if there is a name and other identifying material, then I delete that name, leaving dates and things like regiments, and post a reminder about the privacy policy e.g. Finding service history of ancestor in Abwehr during World War 2?
If there is no name or birth date mentioned, but the question makes me think such an individual may be involved, then I simply post a reminder about the privacy policy e.g. Finding the burial place of British service members killed in WW2
Rather than change, or make any substantial changes, to the current policy I think we could instead direct them to some assistance on how to work within the policy.
I'll offer some thoughts on what that assistance might look like.
How to ask questions about ancestors born less than 100 years ago
Our privacy policy is designed to prevent "identification of any
living (or possibly) living individual by somebody reading this site"
and is not intended to prevent you asking questions that may relate to
someone born during the past 100 years. However, to ask such
questions we ask you to proceed cautiously.
- If you already know that your ancestor was born more than 100 years ago, simply by stating that means that the privacy policy will
not apply so that you can provide details freely. Including the name,
date and place of birth, etc is fine and usually very helpful.
- If you already know (or suspect) that your ancestor was born less than 100 years ago, then it is strongly advised that you do not
include such details in your initial question. Unlike other genealogy
sites, G&FH SE permits you to edit your question to add these data
later, and in the meantime to clarify how to proceed with its users
via comments.
- If you already know (or suspect) that your ancestor is still alive, then under no circumstances can such details be included.
- If you only suspect that your ancestor is dead, then under no circumstances can such details be included.
- If you know (i.e. can prove) that your ancestor is dead, then the onus is on you to provide that proof within your question.
- If you are in any doubt as to whether your proof of death would stand up, then hold back those details, and describe the type of proof
so that other users can help you assess it via comments.
To me the hard part is defining what constitutes proof of death. Clearly a death certificate would, but I suspect that these cannot necessarily be posted here legally. Since we are a reputable website, then I think we should be able to rely on information available on other reputable websites. For example, if war dead are listed on a website, then providing that as a link that shows your ancestor's name should be proof enough. Alternatively, if a newspaper archive contains their death or funeral notice, obituary, or an article about their death then that too should be proof enough for our purposes.
To me, the above would constitute due diligence.
Having now seen the wording of @AdrianB38, I now prefer that over mine, but I think this bit:
Acceptable evidence of death needs to come from some official or
semi-official source such as an entry on a death-registration / grave
/ cemetery / obituary site.
should be changed to something more like:
Acceptable evidence of death needs to come from some official or
semi-official source such as an entry on a death-registration / grave
/ cemetery / obituary site. Please do not just write that such
evidence exists - you will need to include a website link (URL) and
ideally a picture of a newspaper cutting, headstone, etc that enables
independent verification to be quickly and easily performed.
