All of the questions that ask about whether a source is "reliable" all have the same answer. There's no substitute for doing the analysis yourself, and to me these questions seem to ask for permission to skip analyzing the information.
In the don't-ask section of the help center which talks about constructive subjective questions, we see that they should:
invite sharing experiences over opinions
I would like to edit these into questions and ask the question that I think should have been asked in the first place: about how to evaluate the source instead.
There is a valid question lurking in Checking Daughters/Sons of the American Republic (DAR/SAR) lineages?, because the standards of research required for getting in have probably become more rigorous over the decades as the standards of proof have been refined. But answering the question on those grounds ducks the real question about how to evaluate the information.
