Lately we have had a flood wave of "Crazy Magic Hatters" from Wonderland, not looking for Alice, but they seem to have the desire to reveal magic and make the knowldege known for over half of the population around them. This attitude puzzles me. They are a source for the hecklers and "irritating relatives" that like to show the rest, they know how the magic trick is done, even though they have never tried it.
Ethics of magicians are the same all over... or you are not a magician.
One of the golden rules is, never to reveal your secret, be it sleighs or methode.
But would we then get any new magicians in the world?

Oh yes we would. There are always a few that go to libraries and find books there. There are always those who know somebody that can help them out, and a lot of magicians teach magic to an "apprentice" that will become a magician and keep the secrets for years and years. Person to person, the way it has been for centuries, I guess.
But with the Internet, things have changed. It's so easy now to put up a web page or a video and expose magic. Some think this is natural and you can't do anything to stop it. I just think we need a bit of an attitude change, mainly from (as it appears) teen boys. Some of them violate the law, by posting copyrighted material and are so naive, they think they can change the name of, for example: Stigmata to Stigm@t@ to free them for lawsuit.
Of course there have been a few, and mind you... a few magicians that have violated the ethcis, but not by using the Internet.
The Internet posting violators have argued: Why can't we post those things? You can't copyright a move! But they seem to forget that some people make their living from performing magic. Others make living from creating magic and they are being robbed by those violators
Let's take some examples:
There is a huge difference between, for example:
- a grandfather teaching his grand daughter some magic skills.
- a magician that sits in the back room of a magic shop and calls a kid over to teach him some good sleights (true story).
- somebody that goes to the library to find 1 or 2 good books on magic and takes them home for a month.
and then
- some teens posting 100's or 1.000's of sleights, secrets and even copyrighted tricks on a public website, accessable to any laymen that want to be able to heckle a street performer. Some have even posted training vids from PenguinMagic or Ellusionist directly on their websites, which is actually a criminal act.
The ones in the first group are basicly on "one on one" basis, while the 2nd group is revealing magic to tens of thousands of Internet users.
One of the teens argued: Why should magic only be for the rich that can afford to buy boks, DVDS etc.?
I say to contradict that: Why should anything in the world only be for those who can afford to buy it? Shouldn't we just be allowed to steal or take what we like and use anything as we please? I'd love to get a new Jaguar, should I steal one, just because I want to?
No, magic should be for everybody to enjoy, but only for a few to perform.
Or... A friend of mine is so poor, he can't afford to buy the Harry Potter books. Shouldn't I just steal some for him or even make photocopies in the local book store, for him to read? Tsk... tsk... tsk... How naive attitude!
There is a petition here, with almost 1.200 people, asking YouTube to stop revealing magic. That should apply to any other page that teaches (read=reveals) magic.
And there was a brilliant suggestion on TM, asking magicians to change one and one word in Wikipedia, where magic is explained in details. I tried it the other day, changed 3 words on the page about The Pass, and now a week later they are still as I left them, making it impossible for anybody to learn it from that page.

But I think the bottom line is that anybody who wants to relate to magic and call himself/herself a magician, should keep the magician's code and not reveal magic. The others are not worthy to call themselves magicians.
