Thank you for your comments. We're well aware of the pitfalls you're pointing. Some of them can be avoided now, others will need a dose of AI down the road. For now, we log the data when we find it. Mentioning the sources is a tricky issue. Our philosophy is to say as little or as much about everyone. Barack Obama's record is no more developed than yours. Linking a record to Wikipedia or to the list of Minnesota's sex offenders would break that rule, and not in a good way in my opinion.

I didn't immediately understand the point you're making there because I don't think you'd ever need to use Wikipedia or a list of sex offenders as a source, but I think I see your point now: if for 98% of people the specified source is a government register of births then anyone who doesn't have that source mentioned will stick out and an astute reader will immediately infer that they were born in a place where the register of births is not easily accessible or they have changed their name or something like that. So mentioning the sources is, as you say, a tricky issue.
