There's a few BBs whom are pretty popular and prolific in the BJJ community here that were self taught, and that had schools from the beginning (usually as blue or purples). In fact some of the highest ranked BJJ guys here guys that were pioneers in Toronto were self taught, and progressed through the ranks, while having schools, although they indeed had extensive previous martial art training. Only recently a couple Brazilian BBs settled here to either open schools or teach, starting as BBs. Also, Salvosa, one of the guys I speak of, of Salvosa BJJ, is a great inspiration to me in my future ventures.
They affiliated themselves with various BJJ grand masters, Silvia Behring, and Marcus Soares, who is Carlson Gracie's highest ranked BB, and then did a sort of distance learning through them.
There are a lot of Karate studios with very little actual BJJ experience that now have posters popping up in their windows of them doing arm bars, and yes it seems dangerous; however, I'm not going to criticize them too much, because some people are also quite vocal against blues and purples running BJJ schools. It's all very relative.
