well, count me in, but i don't think it's a good idea.
i'd suggest more aggressive, more questionable ways:
everyone gets a youtube account (if he/she doesn't have one), then we start a new thread here where we collect all magic exposers from youtube, and first up we flag the videos (i don't know if that actually does anything, but with a big amount of people it might help), and then we set a certain time when we all at once write a more or less polite message to the user asking him not to expose magic tricks. i can imagine that some of those 9year olds might be impressed by the amount of messages and actually listen to us.
