The video would be considered "doxing". It is, unfortunately, family "dirty laundry." Any video we can manage to record, screen shots of posts, audio recorded, witness testimony, and so on, is more useful in the divorce settlement/ child custody proceedings.

So perhaps it could be, "Go ahead and hit yourself in the face all you want, just NOT IN FRONT OF THE DAMNED CHILDREN!"
