The only thing I can imagine that would excuse it (apart from being a true story after all, which is very doubtful) is that he created the page from a request on "request for article creation" (I don't know the exact name, so can't link it, butwe do have something like that floating around). If that's the case, then he just AGF too much and didn't check enough, which is slightly careless but not a serious mistake. I hope this is the case, otherwise I would indeed raise it at ANI.
