Verification?

Once again, in using one of the major genealogical database sites, I find a lineage extended back further than my research had taken me and also across the ocean to the "mother country" for about 500 years. Quite impressive, right?

However, NONE of the documentation is included, nor a way to contact the researcher to discover the sources. How can we ask for serious academic recognition when we don't document properly? Any reliable data should be cited/fottnoted or the submitter runs the risk of submitting a suspect conclusion and suspect pedigree.

What do you think?
