There's an old thread on this guy:
Rob Tallack - No BS MMA and Martial Arts
and one about his dad:
Karate Club..... a little help?? - No BS MMA and Martial Arts
From a skim of both threads, it seems that a few allegations were thrown around about Tallacks Jr. and Sr. but nothing really bad was ever proven one way or the other, and it ended up being one person's word against that of another - and that several of the claims that people took the time to look into turned out to be true (or 'true, albeit phrased creatively on the website').
Actually I would really support this project if the idea was to make little kids love martial arts and influence them about starting real training under a real instructor, instead of making them believe they can protect themselves with some DVD sets.
There are so many kids that cannot get separated from their TV's or computers these days.
