Hello CXT:
Assorted Helath Club Acts apparently are pretty good for derailing this type of situation. Bunch of criteria I would think, but not a bad route to try if necessary...
Another one I thought up Sorin, have her/yourself visit the local regional/local court house. Look up the school and the head instructor/instructors for civil lawsuits...
Then chat with the suing parties

see how their martial art suits were resolved! Please keep us apprised, lots are interested in this one unfortunately...
