Can't tell you how many times someones marketing claims got them into trouble.
Fakes, frauds, chislers and scam-a-rei they just can't seem to help themselevs.
Educating the public is a neverending task.
The "soke" group you mention is often suspect because they extraordinarly low standards for membership, yet "sound" impressive ot the layperson.
As an aside, I'm not a fan of "continious" sparring unless closely watched---it has similar problems to "point-sparring" unless ITS ALSO closely watched.
Its hard to "continiously" spar after getting hit hard--so what you get is people "pulling" their shots.
Same problem with using the bogu to much, you sorta get dependent on the armor.
IMO, its not "types" of sparring that need to be avoided, its how they are used that matters.
