Yep, which is why I stress the proof of Japan link and actual teacher so much. You cannot find scholars to agree 100 percent on anything it seems. Heck, you want to find people who think the US never went to the moon you can find them. But a Japanese art should have a link to Japan and be known in this country. Many fruads flock to the title of ninjutsu in order to use the excuse of "secrecy' to explain away why they are not known in Japan. But if you can hear about it on the internet, it ain't that secret. Heck, can anyone think of a reason to keep an art secret in the 20th century that does not sound like a bad comic book plot? Same goes for proof of a teacher. Even if my teacher were to die tommorow, the pile of proof in terms of certificates, photos and people who have witnessed me training under him would be overwhelming. So when someone claims to have been taught to the level of grandmastership and can't provide even that, I just have to laugh in their face.
