Re: What do we do?
A couple of data points:
Vu Ha doesn't have a website, just a rather skimpy social networking page for Boston Aikikai that doesn't discuss his lineage at all. Boston Aikikai's home is the Boston Chinatown Neighborhood Center -- it doesn't have its own building.
Phil Traunstein's Long Mountain Aikido is based out of his home in Granby MA.
That's two examples of instructors who meet at least two of your "suspicious" criteria -- and two examples of why one should curb any impulses to try and show up such, um, obvious frauds.
