This seems to be a special case that might happen to any website, or maybe even the big news outlets (it has) or even the American public (with elected legislators later having been found to have fabricated resumes, degrees, etc.) So, it could happen to Ran and Golf Club Atlas, too.
I don't see the shame in it for Ran. If this site stays active for another 25 years, it will probably happen again at some point. I understand its his baby, and important to him, but just how much vetting should a moderator on this type of site do to counter a once in a blue moon attempt at historical forgery? I doubt there are any standards he has fallen below, even if he feels badly for what happened.
I hope it doesn't discourage further IMO pieces, even if not completely researched, but with honest intentions.
First, this isn't really a professional history site. As someone mentioned, its closer to crowd sourcing than old school historic research, even for all the time put in by guys like David Moriarty here in researching my professions history. Once again, kudos to all who do spend the time I wish I could, but can't. I hope the legit work finds an even better repository and audience than this site.
Second, Ron Whitten and other researchers have mentioned more than once that the greatest fear in publishing (especially in print) is that after it comes out, some new information will come out to alter the findings. It is sort of the nature of historic research, as far as I can tell.
Of course, this case is different from that. We can debate how much "shame" Phil ought to feel for being duped, and whether those documents should have ever passed his initial "historian" smell test, but I leave that to others. I don't sense that this is the definitive end to Phil's historical career, depending on how he handles it, but then again, I don't really know how these kinds of things play out.
The thing Ran is most right about is that it is a sad, sad conclusion.
