Re: [WM]: [WM] Protecting from screen capture

["MARY LYNNE HALLOT" <2370447@uwc.ac.za>]

Dear J. Bloom, I have an idea and I hope it will help.
In 1956 N.J. movie theater flashed subliminal messages, "Hungry? Eat = popcorn. Drink Coca-Cola."
This increased popcorn sales 58% and Coca-Cola sales 18% but results were = not replicated as it was felt that people were
subliminally affected and = had no choice in the matter. Psychological warfare it was coined and this = law was forbidden to be
used. Maybe you could put this idea to good use by = ensuring that a message is flashed in the movie at every specific time = frame
asking people to refrain from illegally copying movies. This could = be done in a psychologically intelligent manner which would not
disempower = the person doing the illegal activity, unyet could plead with their sense = of only copying what they themselves
create. Research could be done into = this line of activity. Using the law and psychologists in colloboration = with computer
scientist and graphic Designers. I hope this helps. You have = always been good to me and gone out of your way to aid me. Thank you.
I = have other ideas, but I would rather wait incase my ideas are too over the = top.  Regards
